Filter by:A bacterial infection of an artificial joint is a serious complication that often requires additional surgery to exchange the arthroplasty. It is also difficult to recognize an infected joint, as the symptoms caused by the infection are very similar to those of other problems with arthroplasties, such as loosening of the implant. To improve the ability to diagnose prosthetic joint infections, this study compares the levels of calprotectin, a specific inflammatory protein, in the joint fluid of infected joints and joints with other complications. The underlying hypothesis is that the level of calprotectin in infected joints is significantly higher, thus facilitating the diagnosis of prosthetic joint infection.
Phase 2, randomised, double-blind,double-dummy study in hospitalised adults with complicated urinary tract infection (cUTI), including acute pyelonephritis.Treatment duration for each cohort was 7 to 14 days. Patients were not permitted to switch to oral therapy.
In France, Streptococcus pneumoniae is the leading agent bacterial involved in community lung disease and meningitis. The frequency of these infections and their mortality increase significantly in those at risk such as patients with certain chronic diseases, immunocompromised or on immunosuppressive therapy. This population, despite regular monitoring, has a limited pneumococcal vaccine coverage of around 20%. By carrying out a reconciliation of treatments upon admission to hospital, the clinical pharmacist can detect those without up to date pneumococcal vaccination status. The goal of this management is to make the patient aware of the need for vaccination and organization upon return home. Thus, this limited pneumococcal vaccination coverage would benefit from intervention by regional clinical pharmacy activities. The study investigators want to study the impact of a structured medico-pharmaceutical collaboration on pneumococcal vaccination of patients with risk on discharge from hospital. The investigators hypothesize that this collaboration in patients at risk of infection with pneumococcus could significantly increase their anti-pneumococcal vaccination coverage
This multidisciplinary project aim to understand the epidemiology of the monkeypox in Central African Republic through the identification of the animal reservoir, the clinical and epidemiological description of the human outbreak, through an ethnological approach around risk factors of the disease and through an ecological approach of the ecological context of emergence, and the improvement of biological diagnosis.
Multidrug Resistant (MDR) bacteria have become a major worldwide public health challenge and hospitals are now increasingly faced with management of local outbreaks involving such pathogens. Especially, intensive care units (ICU) provide an ideal background for outbreaks caused by MDR bacteria among which carbapenemase-producing Enterobacteriaceae (CPE) can be found. Among CPE involved in ICU outbreaks, VIM producers have been reported worldwide, and described as especially difficult to control. The COVID-19 pandemic and all of the measures health workers have to implement to fight the spread of SARS-Cov-2 have also impacted the management of such outbreaks. In this retrospective study, the investigators aim to describe the management of an outbreak caused by a VIM-producing Enterobacter cloacae strain during the 2020 COVID-19 pandemic in an ICU, and show the importance of concerted measures and actions implemented at multiple levels to prevent the spread of this MDR strain.
The clinical courses of COVID-19 in children are reportedly mild, and may therefore readily escape diagnosis. Prolonged intestinal virus shedding has been reported in children, thus rendering the pediatric population a potentially important source of virus transmission. However, the infectious potential of SARS-CoV-2 (severe acute respiratory syndrome coronavirus type 2) excreted in the stool has remained enigmatic. The investigators hypothesize that stools carrying the virus can represent a source of infection, at least in a proportion of instances, and therefore intend to screen stools of children admitted to the hospital regardless of the indication in order to assess the frequency of intestinal virus excretion. The screening will be performed by validated RTQ-PCR (reverse transcription quantitative polymerase chain reaction) assays. In positive cases, stool extracts will be used to inoculate permissive cells (e.g. VeroE6) under BSL3 (Biosafety Level 3) conditions, and the infectious potential of the viruses will be determined. The readout will be based on the assessment of cell cytopathic effects and on the expression of subgenomic mRNA. it is expected to recruit ~100 patients for the study. Additionally, the investigators will specifically examine children admitted to the hospital because of COVID-19, and will determine the temporal correlation between viral loads in the upper respiratory tract (URT) and serial stool specimens as well as swabs from the palms and from the oral cavity using RTQ-PCR. Longitudinal studies on the infectious potential of viruses from the URT and stool will be performed using the experimental approach outlined above. For this part of the study, is is intended to recruit ~100 children. Furthermore, samples derived from >200 patients from our biorepository will be used. The insights gained from the study will greatly expand the knowledge on the epidemiological and clinical significance of SARS-CoV-2 infections in children. If stools are identified as a potential source of infection, the data will have an important impact on safety measures in specific settings such as the kindergarten.
It is known that the pretreatment with exogenous interferon blocks SARS-CoV-2 infection, but intervention is much more effective if administered prior to infection. In this study the primary aim is to investigate 28-day regime of nasal interferon gama use in healthy participants for COVID-19 and other respiratory infections prevention.
Intra-abdominal infection is one of the most serious complications after pancreatic resection. The preventive use of antibiotics intraoperatively could reduce the incidence rate of postoperative intra-abdominal infection. According to the previous retrospective study, changes of serum lactate level on postoperative day1 could predict the incidence rate of postoperative intra-abdominal infection. This prospective RCT is to further validate and promote the findings and conclusion.
The study will examine the effect of using Negative Pressure Wound Therapy (NPWT) compared with standard wound dressing among patients undergoing elective open surgery for incisional hernia. The study's main hypothesis is that NPWT will decrease the post-operative incidence of surgical site infections and also improve the patients' quality of life including less scar-related pain and higher cosmetic satisfaction.
Identifying multiorgan sequalae and complications through high quality, prospective matched controlled studies throughout the course of COVID-19 is important for the acute and long-term management of patients and for health systems' planning. Further, it is key to understand the link between acute illness and long term consequences particularly in those already living with other comorbidities such as cardiovascular diseases or cancer. Since the clinical presentation of COVID-19 can resemble a variety of common respiratory infections, describing the distribution of pathogens and the severity of clinical presentation associated with COVID-like illnesses (CLI) infections is important to generate a baseline clinical description by comparing potential long-term effects of PCR-confirmed COVID-19 to those following other respiratory infections. To gain a better understanding of the clinical burden on COVID-19 survivors we will undertake a comparative evaluation within a cohort of PCR-confirmed individuals with COVID-19 vs. those PCR-confirmed symptomatic individuals with other respiratory pathogens plus healthy individuals from the community. The results will inform strategies to prevent long term consequences; inform clinical management, interventional research, direct rehabilitation, and inform public health management to reduce overall morbidity and improve outcomes of COVID-19.
