Filter by:The effect of the COVID-19 pandemic on the emergence and spread of antibiotic-resistant bacteria is largely unknown, especially in low-resource settings. We aim to investigate the prevalence and relatedness of multidrug-resistant bacteria among patients in both COVID-19 and non-COVID-19 wards in two hospitals in Indonesia. Bacterial isolates will be collected from clinical sample and by screening of patients at discharge followed by 30 days after discharge. Aspects of hospital care that may be different in COVID-19 wards versus non-COVID-19 wards and that are considered important determinants for antimicrobial resistance (AMR) will be measured: hand hygiene compliance, use of personal protective equipment, and antibiotic use. Comparison of these data from COVID-19 wards to non-COVID-19 wards will increase our understanding of multidrug-resistant bacteria and provide further insight into the effect of interventions for AMR. The hypothesis of this study are: 1) the prevalence of multidrug-resistant bacteria in COVID-19 wards is higher than non-COVID-19 wards; 2) there is a relatedness of multidrug-resistant bacteria circulating either in the COVID-19 wards or non-COVID-19 wards; 3) the hand-hygiene compliance is lower in the COVID-19 wards than non-COVID-19 wards, however the personal protective equipment use compliance is higher in the COVID-19 wards than non-COVID-19 wards; 4) the antibiotic use in non-COVID-19 wards is better qualitatively; 5) the use of Ciprofloxacin, Gentamicin, and Ceftriaxone in non-COVID-19 wards is higher than in COVID-19 wards.
Background: By the end of 2020, the coronavirus disease (COVID-19) pandemic resulted in over 84 million cases and nearly 2 million deaths. Continued confinement and restriction are expected to negatively affect mental health, however, some individuals are likely to show much less negative impact than others. The characterization and neurobiological determinants of brain resilience vs vulnerability during the pandemic should generate critical knowledge and open future avenues for individually tailored interventions. Objectives: 1. Identify the individual psychobiological determinants of resilience during COVID-19 pandemic. 2. Conduct a non-invasive brain stimulation intervention to modulate the expression of resilience brain networks. Methods: Barcelona Brain Health Initiative participants will be included, encompassing multiple assessments before and during the COVID-19 pandemic. Machine learning techniques will be applied to define brain networks signature of resilience. Subsequently transcranial alternating stimulation will be used during a controlled trial intervention to promote the expression of brain resilience networks. Expected results: The present project should provide critical new knowledge on brain mechanisms underlying resilience and first evidences of the feasibility and impact of modulating brain resilience networks in terms of its effects on mental health of participants.
Retrospective single-center cohort study to evaluate the incidence of colonization by multidrug-resistant organisms (MDRO) in mechanically ventilated patients admitted to a large intensive care unit (ICU) for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection during the second wave of COVID-19 pandemic (October 2020-May 2021) in Lombardy, Italy. As secondary outcomes, the study evaluates the overall incidence of infections during the ICU stay and assesses the risk factors associated to bacterial superinfection and MDRO colonization.
Black and Latino youth may be less likely to get the COVID-19 vaccine than White youth. In this study we will work with community members to come up with ways to help Black and Latino families learn more about the COVID-19 vaccine and get the COVID-19 vaccine. We will test these ideas out in pediatric primary care clinics. This study will help us make sure that all youth have an equal chance of getting the COVID-19 vaccine.
Considering the compelling amount of studies focused on patients in the active phase of COVID-19 disease and the scarcity of studies focused on patient cured from disease aimed at evaluating the sequelae of SARS-CoV-2 infection, the purpose of the study is to investigate whether in patients recovered from COVID-19 disease, SARS-CoV-2 infection has induced: 1) endocrine-metabolic function damage; 2) neuro-psychiatric damage; 3) muscle damage; 4) pulmonary damage; 5) cardiological damage; 6) venous vascular damage; 7) dermatological damage. Patients will be evaluated at baseline (at discharge from infectious and/or pneumology unit) and after 3- 12 months. A better definition of the prevalence and type of sequelae after recovery from COVID-19 disease could significantly improve the therapeutic management and long-term follow-up of these patients, with a relevant impact in terms of health resources and public health.
Guidelines for endourological procedures during COVID-19 have suggested deferring all elective procedures, while obstructed/ infected stones should undergo urgent decompression. At our centre, screening protocols were implemented with prioritization strategies so that elective care could safely continue at deescalated rates. COVID or septic patients underwent emergency decompression, while non-COVID and non-septic patients underwent primary ureteroscopy (URS) or retrograde intrarenal surgery (RIRS). We aim to report our experience with endourological surgery for stone disease during COVID-19.
There is a clear and urgent medical need of developing new medicinal products for COVID-19 since there are poor pharmacological tools to block the progression of patients to cytokine storm syndrome (CSS). To this aim, this Phase Ib clinical study (APTACOVID) pretends to determine whether ApTOLL, in combination with the standard of care, is safe and shows any biological effect) in those patients infected with SARS-CoV-2 who are not developed CSS yet.
This is an open-label and non-randomized study to demonstrate the immunogenicity and safety profile in adults that received the Ad5-nCoV vaccine at least 21 days but no later than 90 days after the first dose of Sputnik V. The non-inferiority hypothesis is used for the evaluation of the exploratory objective. The ratio of Geometric mean titers (GMTs) of SARS-CoV-2 neutralizing antibody in participants on Day 21 post-vaccination of Ad5-nCoV (previously received a 1st dose of Sputnik V) (Group A) and two doses of Sputnik V (Group B) is used for the evaluation of this hypothesis. It is assumed to enroll about 100 subjects for each group. Additionally, 45 participants will be selected from Group A (to enter the immunogenicity subgroup for cellular immune response analysis. According to the above, considering extra subjects for compensating about 10% dropouts, the sample size of Group A is designed to be 450, for Group B is 200. Participants enrolled in Group A (1st dose of Sputnik V plus 1 dose of Ad5-nCoV) must have only received the 1st dose of Sputnik V and the interval between the previous injection (1st dose of Sputnik V) and the day of vaccination with Ad5-nCoV should be between 21 and 90 days. The comparator (Group B) will be the samples stored at the immunology lab of the Buenos Aires University Medical School, corresponding to individuals vaccinated with 2 doses of Sputnik V.
Early identification and treatment of this inflammatory cascade using existing therapeutic strategies with proven safety profiles could change the course and prognosis of COVID-19 infection, reducing mortality rates. Glucocorticoids may modulate inflammation-mediated lung injury and thereby reduce progression to respiratory failure and death
The Post-Acute Sequelae of SARS-CoV-2 (PASC) Autopsy Study is a cross-sectional study designed to define and characterize the epidemiology, natural history, clinical spectrum, and underlying mechanisms of post-acute effects of SARS-CoV-2 infection in a diverse population representative of the general COVID-19 population in the US. The autopsy study will characterize the pathology of PASC in (i) non-hospitalized patients who die 30 days or later from symptom onset of COVID-19, and (ii) hospitalized patients who die 30 days or later after discharge from a hospitalization for COVID-19. The study will include decedents who had previously fully recovered from SARS-CoV-2 infection (i.e., >30 days from onset in non-hospitalized, or >30 days from discharge in hospitalized patients), and decedents who meet clinical criteria of PASC as defined by the recent World Health Organization publication (see Section 5.4 below). The autopsy study will also explore the pathology of acute SARS-CoV-2 infection in a smaller subset of patients who died 15-30 days from symptom onset. This protocol defines the common set of clinical data elements, autopsy procedures for tissue collection, core measures, pathology protocols, shared pathology tissues, data elements, and methodology. Each investigator site is expected to perform autopsies on the decedents to address the pathophysiology of the potential long-term effects of SARS-CoV-2 infection on human health. The Consortium analysis plan aims to address research questions by incorporating: 1) tissue obtained from autopsies performed at each Phase II participant's site; and 2) tissue available from other pathology investigators/autopsy sites within the Consortium.
