Filter by:The first multicenter prospective, randomized, double-blind, placebo-controlled clinical trial of the pentavalent live vaccine for RVI prevention was conducted in Russia among healthy infants aged 2 months at the time of the first vaccination.
Factors associated with severe forms of COVID-19 infection in patients with inflammatory rheumatic diseases (IRD) or Autoimmune Diseases (AID) are unknown. This unprecedented situation leads to empirical and potentially erroneous advice and recommendations for care. Identifying factors associated with severity, in the context of this pandemic, which is expected to last many months, and possibly years, is crucial for future patients. The objective of this work is to identify the factors associated with the occurrence of severe forms of COVID-19 infection in patients with IRD or AID, by combining analysis of 2 large databases.
Wider research context: Since the recognition of SARS-CoV-2 outbreak in 2019, there are now over 126 million COVID-19 cases worldwide with more than 2.7 million deaths. Reports on neurological manifestations vary in prevalence rates (6-84%) and range from mild (headache, hyposmia, myalgia) to severe (encephalopathy, strokes, seizures). Little is known about long-term neurological outcomes of COVID-19 patients. The investigators propose a structured protocol to capture persistent and delayed neurological manifestations, neurocognitive deficits and quality of life (QoL) 3 and 12 months after COVID-19. Objectives: The investigators hypothesize that neurological manifestations and neuropsychological/cognitive deficits can be detected after COVID-19, substantially impact on patients' QoL and can be correlated with structural neuroimaging findings. Main objectives are to assess firstly long-term prevalence rates and natural history of neurological manifestations, secondly neuropsychological/cognitive deficits after COVID-19, thirdly the impact of COVID-19 on measures of mental health, QoL and functional outcome, fourthly to correlate neurological manifestations and distinct neurocognitive deficits with structural MRI abnormalities, and Fifthly to compare these results to age- and sex matched controls hospitalized with pneumonia (Cpneum) and to healthy controls for MRI-data (Chealthy). Approach: The investigators aim to enrol at least 225 patients with COVID-19, in addition to 50 Cpneum and 80 Chealthy. COVID-19 patients will include (group Oóne) outpatients presenting to the hospital, (group two) in-patients not requiring ICU admission, and (group three) patients admitted to the ICU. The investigators will not include asymptomatic patients, patients not presenting to the hospital, and those who do not consent to participate. The standardized protocol includes a firstly a structured neurological examination, secondly olfactory testing, thirdly assessment of QoL, mental health and functional outcome at 3 and 12 months, and fourthly screening for cognitive deficits (at 3 months) and a structured neuropsychological testing (at 12 months) in COVID-19 patients and controls. In a subset of at least 120 COVID-19 patients and 50 controls (Cpneum) high field MRI will be performed at 3 and 12 months. Innovation: The investigators aim to quantify COVID-19 related and specific neurological manifestations and their impact on the individual health condition. The novelty lies in the prospective design, the longitudinal follow-up including and the inclusion of a control group which allows us to explore the natural history of COVID-19 related neurological manifestations. Preliminary analysis of our ongoing 3-month follow-up suggests persistent neurological manifestations and a significant impact of COVID-19 on mental health, cognition and QoL. The investigators believe that our study results likely influence the long-term care of COVID-19 patients and help to identify those, who need further neuro-rehabilitative support
This randomized controlled clinical trial will evaluate the efficacy and safety of proton pump inhibitor, bismuth, metronidazole, and either tetracycline or doxycycline for Helicobacter pylori rescue treatment. The completion of this trial will expand new therapy for the treatment of Helicobacter pylori.
This household-based prospective cohort study aims to stablish the household transmission of Respiratory syncytial virus and S. pneumoniae especially in the elderly and infants/children as well as inter-relationship between S. pneumoniae and Respiratory syncytial virus.
Acute myeloid leukemia (AML) patients are prone to blood stream infection (BSI) due to bone marrow suppression, oral and gastrointestinal mucositis, endovascular tubes, and the application of a large number of broad-spectrum antibiotics. The associated mortality rate is as high as 7.1 %-42%. The use of antibiotics within one hour after the first observation of hypotensive symptoms can guarantee a 79.9% survival rate. For every hour of delay, the patient's survival rate will drop by 7.6%. At present, the blood culture test cycle is long and the positive rate is low. Other infection-related indicators (PCT, CRP) or next-generation sequencing are not highly specific and easy to be misdiagnosed. X-ray, CT and other examinations only have a certain auxiliary value for the infected site. We need new diagnostic tools to accurately identify pathogens. Nano-seq is a next-generation sequencing technology for single-molecule, real-time sequencing and analysis. With ultra-long sequencing read length, it can quickly and accurately identify BSI pathogens types, and give appropriate drug sensitivity results based on drug resistance genes to meet the needs of 99.9% pathogen screening. At the same time, we hope to conduct a prospective evaluation to target high-risk groups of AML prone to BSI in the early stage. The intestine is the body's largest immune organ and the largest reservoir of microbial pathogens. The expansion of certain gut microbiota usually precedes BSI. If there is a correlation between the gut microbiota and MDR-BSI, the colonization and changes of the intestinal flora can be used to predict the risk of BSI in patients during treatment, and preventive measures such as early decolonization or biological intervention will reduce the risk of infection in the future. Combined with Nano-seq and various existing clinical pathogen detection technologies to reduce the occurrence and progress of clinical BSI.
During revision spinal surgery for aseptic indications, there remains a concern that the failure may have resulted from undetectable subclinical infection. In the common revision indications of hardware loosening and adjacent segment disease it is possible that bacterial colonization and low-grade infection precipitated the failure event. There is also significant controversy on the role infectious processes have in the development of degenerative disc disease (modic changes). In particular, this study will investigate whether discogenic colonization with Propionibacterium acnes (P. acnes) can be associated with modic changes. Whereas, in surgery for known spinal infection, epidural abscess and septic revisions, it is possible that standard culture techniques fail to detect polymicrobial flora or accurate speciation. This may lead to inappropriate antibiotic management that is not addressing the range of pathology present. There remains an incomplete understanding of the role that subclinical infection plays in aseptic spinal revision surgery and degenerative disc disease
Study Design: This is a double-blind, placebo-controlled, Phase 3 clinical efficacy study evaluating NONS in adult volunteers as a treatment for high-risk asymptomatic and symptomatic individuals with mild COVID-19 infection. thru facility).
The purpose of this study is to assess the feasibility of TrueLoo™, an Internet-connected smart toilet seat, in accurately monitoring and logging bowel movements and urinations of residents in senior living facilities across Northern California.
It is a single-center, randomized, open-label, phase IV study for the explorative investigation of the pharmacological mode-of-action of Echinaforce® extract in the form of Echinaforce® Chewable tablets"- Further, it is aimed to evaluate the effectiveness of the study product for the prevention and treatment of respiratory tract infections in generally healthy adults following a real-life setting. The study covers 2x2 + 1 month of prevention in 120 randomized participants following a tight sampling set-up for sensitive detection of viral infections by RT-qPCR analysis of nasal swabs and seroconversion of SARS-CoV2 IgG/IgM in serum samples.
