Filter by:With the knowledge of currently transmitted omicron variant being less virulent, over 90 percent of the Chinese population is fully vaccinated, and the Chinese health workers have sufficient experience treating the illness. China 's epidemic prevention and control has entered a new stage to restore the normal functioning of society and basic medical services, On Dec, 7, China released a circular on further optimizing its COVID-19 response, announcing 10 new prevention and control measures.This has marked the watershed for sharply increased number of elective surgical patients diagnosed with COVID-19 during preoperativley, fully recovered or during recovery. Beijing faced a wave of omicron infection starting that would result in of a wide range of population infections. At which time there is limited evidence regarding the optimal timing of surgery following SARS-CoV-2 infection especially for omiron among Chinsese patients .This study intends to explore the relationship between the incidence of postoperative complications after elective surgery and COVID-19 infection in Peking Union Medical College Hospital, and provide data support for the policy formulation of elective surgical timing for patients after COVID-19 infection.
The goal of this national multicenter prospective cohort study is to learn about the added value of 18F-FDG (18F-2-fluoro-2-deoxy-D-glucose) PET-CT in invasive fungal disease management. The main questions it aims to answer are: 1. Does the use of 18F-FDG PET-CT allow a better characterization of invasive fungal infection (IFI) (performance) compared to the exclusive use of conventional radiological studies in terms of extension/staging and monitoring of response/follow-up ? 2. Does the systematic and protocolized use of 18F-FDG PET-CT in IFI allow a better management of patients with IFI and increase the prognostic value of the initial evaluation? Participants will undergo systematically a 18F-FDG PET-CT as part of the work-up of their invasive fungal disease. Researchers will compare the performance of 18F-FDG PET-CT with standard management without 18F-FDG PET-CT to see if adds value (diagnostic, prognostic, and changes in management).
The goal of this clinical trial is to test the effectiveness of an integrated infectious disease/substance use disorder (SUD) clinical team intervention approach in patients hospitalized with severe injection-related infections (SIRI) who use drugs. The main question this study aims to answer is whether this intervention approach will be associated with lower mortality and fewer hospital readmissions. Participants will participate in the integrated SUD/ID care team intervention (SIRI Team). Researchers will compare this intervention to treatment as usual (TUA) to see if there are any differences in health outcomes.
Prospective observational cohort consisting of all adult patients admitted to participating critical care units (ICU and CCU) during the study period, with blood cultures collected as part of their care, and who did not express any objection to participating. For each patient, data will be collected prospectively for each blood culture set collected.
This study aims to observe the impact of COVID-19 infection on the reproductive function and assisted pregnancy outcome of infertile couples undergoing assisted reproductive technology and to determine which factors are related to the clinical pregnancy rate. A multicenter, prospective, observational cohort study was adopted. Infertile couples who met the selection criteria were included in this study, the SAS anxiety self-rating scale was filled out, the basic situation was observed, and blood samples and related tissues were collected for testing. Relevant reproductive function, laboratory, clinical, and psychological indicators were collected, and the correlation between the above indicators and the outcome of the ART-related pregnancy were analyzed.
In Mexico City, the main cause of mortality among people living with HIV (PLHIV) continues to be opportunistic infections (OIs). Early detection of OIs allows their timely treatment and improves their prognosis. The use of rapid diagnostic tests (RDT) based on antigens of the most frequent causative agents of OIs allows adequate screening of these patients and facilitates decision making at the point of care. Unfortunately, these studies are not widely available in the different PLHIV care centers in the CDMX. We will conduct an open-label, non-inferiority uncontrolled clinical trial to investigate the diagnostic performance of urinary lipoarabinomannan, urinary Histoplasma antigen and serum Cryptococcus antigen in patients presenting for care with advanced HIV in CDMX, supported by rapid cluster of differentiation 4 (CD4) testing with lateral flow technology. Four referral hospitals will participate over 12 months. All patients with diagnosed HIV disease and suspected advanced disease presenting for care at participating centers will be included in the study. An inventory of approximately 1000 RDT will be obtained and distributed among the participating sites. A study coordinator will be hired and will visit each site once a week to collect the study variables and follow up on the included patients. The primary outcome of the study will be the percentage of patients with advanced disease who present with diagnoses made by RDT compared to historical controls of patients diagnosed with OI in 2022 at participating centers by conventional methods. Secondary outcomes will be time to initiation of antiretroviral therapy (ART), time to initiation of OI treatment, and 30-day mortality after HIV diagnosis.
The goal of this observational study is to learn about the effects of coronavirus infection in patients with early-stage lung cancer. The main question it aims to answer is whether the interval of surgery and COVID-19 infection will affect the surgery and prognosis of the patients.
The study aims to evaluate the efficacy of negative pressure wound therapy (NPWT) compared with primary closure (PC) in surgical site infection (SSI) prevention for laparotomy for peritonitis.
Background: Epstein-Barr virus (EBV) causes most cases of infectious mononucleosis (mono). Mono can cause fatigue that lasts more than 6 months, and some people can have severe complications. EBV infection may also contribute to some cancers and autoimmune diseases. Currently, there are no approved therapies or vaccines for EBV infection. Objective: To test a vaccine against EBV. Eligibility: Healthy people aged 18 to 25 years. Design: Participants will be screened in 2 parts. They will have a blood test. If that test shows they have never had an EBV infection, they will have a second clinic visit. They will have a physical exam, with blood and urine tests. A cotton swab will be rubbed on their gums to collect saliva. Participants will receive 2 injections into a shoulder muscle. Some will receive the EBV vaccine. Others will receive a placebo; this contains harmless salt water with no vaccine. Participants will not know which one they are getting. The 2 injections will be 30 days apart. Participants will be asked to record any side effects or symptoms they have between visits. They can do this on paper or online. Participants will return for a follow-up visit 60 days after the first injection. They will have follow-up visits by phone or telehealth after 5 and 8 months. They will return for a physical exam after 13 months. They may come back for an optional physical exam after 2 years. Participants will come to the clinic if they become ill with an EBV infection during the study.
The goal of this observational study is to compare the immune function and infection mechanism of patients with hematologic tumors and those people without underlying diseases after infection with SARS-CoV-2. Clinical characteristics, treatment options and responses will be collected. Peripheral blood will be collected from patients with hematologic tumors infected with SARS-CoV-2 and those people without underlying diseases infected with SARS-CoV-2.
