Filter by:Perineal injury following childbirth can result in complications such as wound infection. The perineum has closely related anatomical structures including the external genital organs and the anal triangle which contains the anal sphincter muscles. Therefore as wound infection can extend and as muscles of the perineum sit in such close proximity to each other, the anal sphincter muscles could potentially be affected. This could also potentially include cases of perineal injury where the anal sphincter was not injured. However ultrasound has never been used to investigate this. Endoanal ultrasound is the gold standard diagnostic tool in the assessment of obstetric anal sphincter injury. The anal sphincter can also be visualised using multiplanar transperineal ultrasound(three/four-dimensional. Therefore both modalities could be used. However, it has been shown that transperineal ultrasound has a high positive predictive value and therefore is able to correctly identify an intact anal sphincter, but low positive predictive value; meaning poor detection of sphincter defects. Therefore, although it cannot completely substitute endoanal ultrasound (the gold standard in investigating obstetric anal sphincter injuries), it provides and adjunct/alternative for women who cannot tolerate endoanal ultrasound. The investigators plan to perform an observational study to evaluate to the natural history of perineal wound infections. Patients will be assessed weekly with endoanal ultrasound and/or transperineal ultrasound until the wound infection has resolved and the wound has clinically healed. If a bacterial wound swab has not been taken prior to recruitment or wound swab results are not available, one will be taken to detect the causative organisms. Appropriate antibiotics will then be given to cover the detected organism. Bacterial burden and will also be measured weekly using the MolecuLight i:X; a bacterial autofluorescence camera which captures the presence and load of bacteria. In wounds that have superficially dehisced; exact wound measurements including wound surface area, depth, volume and healing progress will be precisely measured using the Silhouette® 3D camera
HIV infection, as well as exposure to opioids (including heroin), are associated with systemic immune activation including increased microbial translocation from the gut. The overall objective of this study is to define the impact of long-term mu-opiate receptor stimulation or blockage with medication for opiate use disorder (i.e, methadone, buprenorphine/naloxone, or extended-release naltrexone) on the kinetics and extent of immune reconstitution on HIV-1 infected people who inject opiate and initiating antiretroviral therapy.
The study aims to assess the antibacterial effect and symptoms-relief of Qingfei Granule in the patients with pediatric acute upper respiratory tract infection with bacterial infection.
The overall objective of the study is to determine the therapeutic effect and tolerance of Tocilizumab combined with Dexamethasone in patients with moderate, severe pneumonia or critical pneumonia associated with Coronavirus disease 2019 (COVID-19). Tocilizumab (TCZ) is an anti-human IL-6 receptor monoclonal antibody that inhibits signal transduction by binding sIL-6R and mIL-6R. The study has a cohort multiple Randomized Controlled Trials (cmRCT) design. Randomization will occur prior to offering Dexamethasone alone or Dexamethasone +Tocilizumab administration to patients enrolled in the CORIMUNO-19 cohort. Tocilizumab will be administered to consenting adult patients hospitalized with COVID-19 either diagnosed with moderate or severe pneumonia requiring no mechanical ventilation or critical pneumonia requiring mechanical ventilation. Patients who will chose not to receive Tocilizumab will receive standard of cares. Outcomes of Tocilizumab-treated patients will be compared with outcomes of standard of care (including Dexamethasone) treated patients
This study is investigating the role of allergic (Th2) inflammation in patients with Cystic Fibrosis (CF) and history of fungal infection and/or Allergic Bronchopulmonary Aspergillosis. Little is known about fungal infection in CF and conflicting results exist on whether this results in worse lung function over time. There is concern that persistent fungal infection can result in worse clinical outcome measures in patients with CF. Also, it is unclear how ABPA develops, but may be related to the amount of fungus a patient with CF is infected with. This study looks at inflammatory patterns and allergic responses to fungal elements to help identify biomarkers and signs of allergic disease in fungally infected patients with CF.
The study aims to compare the conventional pull-percutaneous endoscopic gastrostomy (pull-PEG) with a pull-PEG with gastropexy suture regarding the peristomal infection rate.
Surgical site infection (SSI) is the main complication of surgery. The prevention of superficial SSI by topical prophylaxis is controversial. Human studies on wound lavage with topical solutions (saline, antiseptics or antibiotics) are old and do not yield conclusive results. In experimental conditions there is evidence in favor of the efficiency wound lavage with saline and antibiotic solutions. Clinical studies are needed to demonstrate the safety and efficacy of antibiotic lavage. Objective. Study of the efficacy of topical antibiotic therapy in the prevention of SSI in patients undergoing abdominal surgery with different risk of infection. Method. Project comprising several randomized double-blind clinical trials with a common methodology. Procedures with varying degrees of contamination, as emergency abdominal surgery, cesareans and complex abdominal wall reconstructions will be studied. Follow-up will be 30 days after operation. Data will be collected anonymously and the relationships between the variables will be analyzed using Pearson's chi-square, survival analysis and analysis of risk factors as appropriate. The effect of topical antibiotic on hospital stay, resistance patterns in SSI, and antibiotic serum levels will be analyzed.
This is part of a feasibility study to compare the predicate standard FDA cleared test for serum to a point of care test Toxoplasma ICT IgG-IgM BK produced by LD Bio Diagnostic. The specificity and sensitivity in testing serum and whole blood will be compared. This study includes 70 persons either pregnant or non pregnant. This is being done in accordance with FDA requirements for clearance of a testing device . The investigators will use a standard FDA cleared test in all studies. The FDA has suggested that the investigators submit a pre subQ for a 510K and dual CLIA waiver. This allows the investigators also to determine feasibility of use of the predicate test in conjunction with the experimental test with volunteers, including men, women, and pregnant women.
In sub-Saharan Africa, non-typhoidal Salmonella (NTS) are a frequent cause of bloodstream infection, display high levels of antibiotic resistance and have a high case fatality rate (15%). In Kisantu hospital in the Democratic Republic of Congo (DR Congo), NTS account for 75% of bloodstream infection in children and many children are co-infected with Plasmodium falciparum (Pf) malaria. NTS bloodstream infection presents as a non-specific severe febrile illness, which challenges early diagnosis and, as a consequence, prompt and appropriate antibiotic treatment.Moreover, at the first level of care, frontline health workers have limited expertise and diagnostic skills and, as a consequence, clinical danger signs that indicate serious bacterial infections are often overlooked. Basic handheld diagnostic instruments and point-of-care tests can help to reliably detect danger signs and improve triage, referral and the start of antibiotics, but there is need for field implementation and adoption to low-resource settings. Further, it is known that some clinical signs and symptoms are frequent in NTS bloodstream infections. The integration of these clinical signs and symptoms in a clinical decision support model can facilitate the diagnosis of NTS bloodstream infections and target antibiotic treatment. The investigators aim to develop such a clinical decision support model based on data from children under five years old admitted to Kisantu district referral hospital in the Democratic republic of the Congo. While developing the model, the investigators will focus on the signs and symptoms that can differentiate NTS bloodstream infection from severe Pf malaria and on the clinical danger signs that can be assessed by handheld diagnostic instruments and point-of-care tests. The deliverable will be a clinical decision support model ready to integrate in an electronic decision support system.
The purpose of this epidemiologic study is to estimate the prevalence and incidence of anti-SARS-CoV-2 antibodies in at-risk, exposed, affected populations. The study will also estimate the risk of SARS-CoV-2 exposure in target population.
