Filter by:The purpose of this study is to evaluate the vaccine efficacy (VE) of a heterologous vaccine regimen utilizing Ad26.Mos4.HIV and aluminum phosphate-adjuvanted Clade C gp140 and Mosaic gp140 for the prevention of HIV-1 infection in HIV-1 seronegative cis-gender men and transgender individuals having sex with cis-gender men and/or transgender individuals.
ACTHIVE-001 is a randomised, open-label, uncontrolled phase 1 clinical trial to determine the safety profile of the native-like HIV-1 envelope vaccine, ConM SOSIP.v7, adjuvanted with monophosphoryl lipid A (MPLA) liposomes. The study will furthermore determine the extent to which the vaccine influences the breadth of viruses neutralised by induced antibodies and the associated diversity of B and T cell responses. The research will also investigate the effect of a within-schedule successive dose level reduction (i.e. fractional dose boosting), aimed to induce higher levels of somatic hypermutation and broadly neutralising antibodies. The primary outcome will be measurement of adverse events. Secondary and exploratory outcomes will include specific viral neutralisation activity of serum antibodies and characterisation of antigen specific blood and lymph node B and T cell responses.
The purpose of this study is to evaluate the safety and tolerability of MEDI8897 compared to palivizumab when administered to preterm infants entering their first RSV season and children with chronic lung disease (CLD) and congenital heart disease (CHD) entering their first and second RSV season.
The purpose of this study is to determine if use of the CleanHands system can improve hand hygiene/personal protective equipment (PPE) compliance and reduce infections in the hospital ICUs through reminders to wash hands and use PPE as appropriate.
This project aims to produce synthetic bone tissue graft that supports bone regeneration and combats infection simultaneously, according to industry standards and regulations. This original and high value added biomaterial "silver doped calcium phosphate based synthetic bone tissue " will be used in clinical trials in patients with osteomyelitis and implant-related infections for the treatment. Chronic bone infections are one of the most important problems in orthopedic surgery and are not just a problem of developed societies. When open fracture cases, which may get infected in 1-50%, implant-related infections and diabetic foot ulcer cases are taken into consideration, osteomyelitis will be seen as a very common problem all over the world. Multiple surgeries, long-term use of antibiotics and the high costs affects all societies. The use of synthetic bone grafts is growing faster than the natural bone grafts in the world. USA has spent 246 million US dollars for the use of synthetic bone graft in 2010. For the treatment of bone infections antibiotic impregnated synthetic bone grafts with different characteristics are used. Although these antibiotic impregnated synthetic bone grafts are superior compared to antibiotic bone cement with the implementation of different antibiotics and to be absorbable but they cannot show optimum benefit because the release of antibiotics is not due to host matrix degradation but diffusion control. The other issue to be considered as this regard that the development of microbial resistance to these antibiotics which is also a serious problem. Innovative synthetic bone graft with better contribution of the needs of mechanical properties, depending on the applied bone region, optimized antimicrobial activity and bone tissue regeneration are needed. In this study, it will be determined whether this silver ion -doped antimicrobial synthetic bone graft that has the capacity to fill the bone voids that may occur in chronic bone infection during disease process or after surgical debridement, also has the capacity to treat the infection in the bone will be used in 12 patients who had been diagnosed as chronic osteomyelitis to see if it cause any unwanted side effect in normal usage conditions and generates unacceptable risks. Clinical, laboratory and radiological investigations will be used to demonstrate the healing of the infections and the cavities in the bone. Blood and urine levels of silver will be detected from patients. Antimicrobial activity of silver is well-known. The effectiveness of the silver and potential toxicity is related to the dose of silver and application form. In orthopedics, the use of silver is mostly limited to elemental silver coating of metal implants. There is no biotechnologic approach manufactured silver ion -doped calcium phosphate -based synthetic bone graft in the health sector yet. Ionic silver has advantages such as low toxicity, no tolerance of silver against bacteria, and strong antibacterial activity. The trapping of silver ions in the calcium phosphate based ceramic structure overcomes the other systems with its controlled release and its ability to be effective at minimum doses. The project is an original work since it will contribute to bone regeneration while at the same time removing the infection.
This is a study to determine if the incidence of infection at the Surgical SitE is impacted if with Antibiotic Irrigation is used during Ventral Hernia Repair (RINSE Trial)
This will be a multistate, multicenter clinical study to determine the efficacy and safety of medical cannabis for a wide variety of chronic medical conditions.
In the general population, increased WBCC and neutrophil count are widely used as markers for infection during inflammatory states 1. However, 32% of geriatric patients with an infection do not develop an increase in WBCC 2. The hypothesis is that with inflammation, geriatric patients have a misadapted response of the immune system (IS) 3. Our recent retrospective study 4 has shown that total and differential WBCC were not correlated with infection in a geriatric hospitalized population. Therefore, WBCC does not seem to be a reliable marker for infection in geriatric hospitalized patients. The neutrophil/lymphocyte ratio, and CRP, seem to be better markers. the aim of the study to investigate this hypothesis prospectively and assess the role of aging and chronic diseases (such as cardiovascular diseases (CVD) and risk factors (CVRF) 5, cytomegalovirus (CMV) infection 6, periodontitis 7, onychomycosis 8 ) in this process and assess the role of a geriatric assessment. To assess the usefulness of WBCC in the diagnosis of infection in geriatric patients and to address the contribution of ongoing chronic co-morbidities and age to WBCC-kinetics during an acute inflammatory syndrome, young and geriatric hospitalized patients with an inflammatory syndrome with and without infection will be compared
The study will explore the impact of a nurse-led bundled antimicrobial stewardship intervention on the appropriateness of antimicrobial use in residential aged care facilities. The intervention will be assessed in a stepped-wedge cluster randomised controlled trial across 14 residential aged care facilities over an 18-month period.
People who inject drugs (PWID) have increased risk of Staphylococcus aureus (S. aureus) colonization, skin and soft tissue infections (SSTI), and systemic infections like septicaemia and endocarditis. International research and data from Malmö needle exchange program (NEP) show a 60 - 70% lifetime SSTI prevalence. Longitudinal colonization pattern of S. aureus and its association with infection frequency among PWID is unknown. Cultures from the anterior nares, throat and perineum are used to indirectly assess S. aureus skin colonization. In PWID 28 - 45% are colonized in the nares, which increases risk of infections. Clinical significance of extra-nasal colonization, and persistent/intermittent colonization is uncertain. The S. aureus genome can be characterized by whole genome sequencing (WGS). Certain types are associated with abscesses and systemic infections. The infection pattern among PWID is unknown. S. aureus skin colonization level is decreased by chlorhexidine body wash and nasal mupirocin used as surgical prophylaxis and treatment of furunculosis. To our knowledge, disinfection effect on infections in PWID is not studied. However, the clinical impression is that severe infections have somewhat diminished since the NEP started distributing skin disinfectant tissues. RESEARCH QUESTIONS 1. Can repeated skin wash with chlorhexidine decrease infection frequency among PWID? 2. Is the longitudinal S. aureus colonization pattern associated with infection prevalence among PWID? 3. Can the risk of S. aureus-infections be predicted by quantification of bacterial level in anterior nares, throat, perineum or skin lesions/eczema? 4. Can different types of S. aureus be identified, that are associated with colonization or infection among PWID (by WGS)? METHODS AND TIME PHRAME Malmö NEP was established in 1986, and several studies assessing HIV, hepatitis and sociological questions have been conducted in this setting. In December 2016 continuous inclusion of 100 PWID for the actual study started at Malmö NEP. The study period is estimated to two years, with scientific papers expected for publication. During the first year of the study, mapping of S. aureus colonization pattern among all study participants is conducted by repeated sampling, clinical evaluation of eczemas, and interviews regarding infections. Every third month samples are collected from nares, throat, perineum and skin lesions. Semi quantification of S. aureus takes place at the microbiological research laboratory at Lund University. BBL CHROMagar Staph aureus-plates are used and incubated in 35oC air for 48h. S. aureus-colonies are identified and quantified manually by pink colour change and Pastorex. MALDI-TOF will be used in unclear cases. Disk-diffusion will be used for resistance determination. Bacterial isolates will be frozen to -70oC for later WGS. Intervention with chlorhexidine wash starts one year after inclusion for each study subject, and will continue for one additional year. Study participants with S aureus colonization will undergo regular showers with chlorhexidine (intervention group) at the needle exchange. In order to avoid bacterial resistance, muporicin will not be used. During the intervention, cultures, interviews and clinical evaluation will continue.
