Filter by:The goal of this observational study is to test whether the dynamic changes of CD4+T lymphocytes can predict infections in patients with primary nephrotic syndrome . The main questions it aims to answer are: - whether the dynamic changes of CD4+T lymphocytes can predict infections in patients with primary nephrotic syndrome - effect of different immunosuppressive therapy on the number and function of T lymphocyte subsets in patients with primary nephrotic syndrome Participants will be divided into infection group and non-infection group according to whether they are infected
Approximately 8% of all births occur between 30-36 weeks of gestation ('moderate-late' prematurity). Respiratory tract infections (RTI) and wheezing illnesses disproportionally affect preterm infants resulting in a 1.5-2 fold higher hospitalisation rate during the first years of life compared to term born children. Besides prematurity, several other postnatal modifiable influencing factors are associated with increased risk of respiratory morbidity and impaired pulmonary development. These factors include RTI, rapid weight gain, air pollution, tobacco smoke exposition, vitamin D deficiency, maternal stress and antibiotic usage. The investigators hypothesize that a follow-up program aiming at prevention of modifiable influencing factors can reduce respiratory morbidity in moderate and late prematurity. Objectives: To reduce respiratory disease burden in moderate-late preterm infants in the first 18 months of life
The BK virus (BKV) belongs to the Polyomaviridae family. The primary infection, generally asymptomatic, occurs during childhood. The virus then persists in latent form in the body, mainly in the epithelial cells of the kidney and urinary tract. Cellular immunosuppression favors BKV replication. It is responsible for pathologies of the renal-urinary tract such as BKV-associated nephropathy (BKVAN) in kidney transplant recipients, hemorrhagic cystitis (HC) in hematopoietic stem cell (HSC) recipients or ureteral stenosis. To date, there is no specific antiviral treatment against BKV. The management of patients is essentially symptomatic and requires a multidisciplinary approach. It is therefore necessary to identify early prognostic markers for the occurrence of CH and to develop new therapeutic strategies.
A phase 2, multi-center, double-blind, randomized, placebo-controlled study to evaluate the safety, phage kinetics, and efficacy of inhaled AP-PA02 administered in subjects with non-cystic fibrosis bronchiectasis and chronic pulmonary Pseudomonas aeruginosa infection.
Appropriately, half of the global population is infected with H. pylori, and it is now recognized that it causes at least 95% of all gastric cancers. Currently, the main challenge in the field of H. pylori infection is the rapidly increasing antibiotic resistance worldwide, which is causing a decline in the effectiveness of currently available eradication regimens. The aim of the study is to assess the safety and efficacy of different H. pylori vonoprazan-based regimens compared to the commonly used standard triple therapy composed of Clarithromycin, Amoxicillin, and Proton pump inhibitor to eradicate H. pylori infection in treatment-naive patients through the determination of each regimen eradication rate and reported safety profile
Geographic Information Systems (GIS) and spatial analysis have become important tools in public health informatics but have rarely been applied to the hospital setting. In this study we apply these tools to address the challenge of Hospital Acquired Infections (HAIs) by building, implementing, and evaluating a new computer application which incorporates mapping and geographic data to assist hospital epidemiologists in identifying HAI clusters and assessing transmission risk. We expect that incorporation of geographic information into the workflow of hospital epidemiologists will have a profound effect on our understanding of disease transmission and HAI risk factors in the hospital setting, radically altering the workflow and speed of response of infection preventionists and improving their ability to prevent HAIs.
This study is being performed to see if 18F-FDS is a useful imaging agent for diagnosis of bacterial infections. Position Emission Tomography (PET)/ computed tomography (CT) scans will be obtained after intravenous injection of 18F-FDS to determine biodistribution and pathophysiology in diseased subjects.
General anesthesia, thoracic epidural, and morphine inhibit the urination process and promote postoperative Acute Urinary Retention (AUR) after thoracic surgery. Indwelling bladder catheterization prevents this risk, but is associated with other complications (urinary tract infection, delayed mobilization). With the rise of enhanced recovery after surgery (ERAS) protocols, bladder catheterization is being questioned. The current protocol in the department is to catheterize only patients with a high bladder volume in the post anesthesia care unit (defined as a bladder volume > 400 ml on bladder scan). Preliminary results from the "AirLeaks" study show a high rate of early postoperative AUR (approximately 50%). The investigators believe that a "systematic intermittent catheterization" (SIC) strategy is superior to the current "bladder scan-guided catheterization in the post anesthesia care unit" (BSGC) strategy in preventing the risk of postoperative AUR. To their knowledge, no study has compared these two bladder catheterization strategies in a thoracic accelerated rehabilitation protocol.
Citizens who undergo testing for COVID-19 at one of two Testcenters in Copenhagen Captial Region will be invited to participate in the study. The participants will be randomized to either an oropharyngeal swap including the palatine tonsils OR an oropharyngeal swap without the palatine tonsils for SARS-CoV-2 testing. The swabs will be sent to the clinical microbiology laboratory for SARS-CoV-2 detection using RT-PCR. The diagnostic accuracy and SARS-CoV-2 viral load will be compared. The participants will be asked to complete a questionnaire regarding their symptoms.
Tuberculosis (TB) is one of the top ten causes of death worldwide with approximately 10 million cases globally and 1.2 million deaths. Sub-Saharan Africa carries the highest burden of TB. South Africa has one of the highest HIV and TB rates worldwide with an HIV prevalence rate in adults of 19% and a TB case notification rate of 615/100,000 in 2019. Over many years, focus has been paid to pulmonary TB and extrapulmonary TB (EPTB) has received only little attention even though it accounts for almost a quatre of all TB cases. The diagnosis of EPTB remains challenging simply because sample collection requires invasive procedures in the absence of a blood-based diagnostic test. Spinal TB (spondylitis or spondylodiscitis caused by Mycobacterium tuberculosis) - often known as Pott's disease - accounts for up to 10% of EPTB and affects young children, people with HIV-coinfection and elderly, and often leads to lifelong debilitating disease due to devastating deformation of the spine and compression of neural structures. Little is known with regards to the extent of disease and isolated TB spine as well as a disseminated form of TB spine have been described. The latter presents with a spinal manifestation plus disseminations to other organs such as the lungs, pleura, lymph nodes, the GIT or urinary tract or even the brain. In the Spinal TB X cohort, the investigators aim to describe the clinical phenotype of spinal TB using whole body PET/CT and identify a specific gene expression profile for the different stages of dissemination and compare findings to previously described signatures for latent and active pulmonary TB. A blood-based test for spinal TB would lead to earlier diagnosis and treatment in all settings globally and improve treatment outcome of this devastating disease.
