Filter by:Only a fraction of individuals infected with microbes develop clinical disease. This observation raises fundamental questions about the pathogenesis of infectious diseases. There is a complex interaction between environmental (microbial and non-microbial) and human (genetic and non-genetic) factors. This will determine the quality of the immune response against the infectious agent and the clinical manifestation. By definition, individuals who die from an infection have defective immunity to the pathogen in question (immune agent (immune deficiency). The investigation of individual variability in the development of infectious diseases began in the early 20th. The first evidence to support the hypothesis that individual variability variability and immune deficiencies were hereditary came from observations of familial cases or genetic isolates genetic isolates (from a homogeneous population) of rare or common infectious diseases, which in some cases Mendelian heredity hat predisposition to infectious diseases runs in families even more so than diseases associated with less determined environmental factors, such as certain cancers. such as certain cancers. Finally, studies comparing the rate of concordance of infectious diseases between monozygotic and dizygotic twins also implicate genetic factors in disease susceptibility. These observations were validated by the discovery of genetic defects associated with severe infectious diseases, leading to proof of concept. While a number of hereditary immune deficiencies associated with susceptibility to multiple pathogens or microorganisms, a growing number of new and rare new and rare immune deficiencies conferring restricted susceptibility to infections caused by a single caused by a single pathogen family, or even a single pathogen, in otherwise healthy children, have recently been identified (one gene, one pathogen). As a result, a dozen Mendelian clinical syndromes characterized by restricted susceptibility are now known. Over the last 20 years, it has been proven that these "idiopathic" infections were immune deficiencies. The investigators now wish to study new severe infections, including but not limited to viral, fungal and bacterial infections. viral, fungal, bacterial and parasitic infections. This should lead to a better understanding of the pathophysiology of each disease, the development of new therapeutics and better patient care.
Bacterial infections among young infants, including sepsis, meningitis, and pneumonia, continue to cause a substantial number of deaths globally. Zinc supplementation in combination with standard antibiotic therapy may represent a new intervention to reduce mortality and improve treatment outcomes for young infants with clinical severe infection. The Investigators will conduct a randomized, double-blind, placebo-controlled trial of zinc supplementation among young infants 0-59 days with severe clinical infection. The trial will enroll 3,250 Tanzanian infants hospitalized with clinical severe infection as defined by WHO Integrated Management of Childhood Illness (IMCI) guidelines. Enrolled infants will receive standard clinical management including antibiotics and will be randomized to receive either a 14-day course of twice-daily 5 mg elemental zinc (10 mg per day) or a matching placebo regimen.
In chronic hemodialysis patients, bacteremia is most commonly caused by dialysis catheter infections. It is estimated that the vast majority (52-84%) of these infections are due to Gram-positive cocci, particularly Staphylococcus aureus (21-43%). Penicillin M (oxacillin and cloxacillin in France) is the reference beta-lactam for the treatment of invasive methicillin-sensitive S. aureus (MSSA) infections, but has not shown a prognostic benefit in large retrospective cohorts comparing penicillin M and cefazolin, at the expense of more frequent adverse events. Dosage in the chronic hemodialysis population is unclear because it is based on old studies.
The neurogenic bladder and bowel are two pathological conditions occurring when damaged innervation results in functional alteration of both the bladder and the bowel with a clinical presentation that can vary from retention to incontinence often associated with an increased risk of infection. Specific microbiological patterns of urinary microbiota are associated with states of well-being of the host and play protective and preventive functions for numerous urological pathologies such as urinary tract infections, urinary incontinence and bladder tumors. What the "healthy" profile of the bladder microbiota is in subjects with neurogenic bladder appears currently poorly reported in literature data. Indeed, in these populations different strains of uropathogenic microorganisms, such as E.Coli, Klebsiella, Pseudomonas and Enterococcus, are dominant compared to healthy subjects where Lactobacillus predominates. The characterization of the gut microbiota in terms of composition can be a key tool for understanding the effects that preventive therapeutic and nutritional approaches or clinical procedures have on it, subsequently offering the possibility of improving and complementing these treatments. Among human microbiota, the vaginal one, the "vaginoma", is among the most studied for its correlation with female health status. The "core" of the vaginal microbiome is Lactobacillus which under physiological conditions is represented in particular by Lactobacillus Crispatus, Lactobacillus Iners, Lactobacillus Jensenii and Lactobacillus Gasseri. Immune cells and related PRRs receptors interact with the microorganisms in the vaginal environment of the vaginal environment are the immune cells and the related PRRs receptors thus the close relationship between microbiome and immunity as well as between vaginoma and genitourinary well-being is now evident. The characterization of the gut, urinary and vaginal microbiota in patients with neurogenic bladder secondary to spina bifida and multiple sclerosis can help identify a "health promoting" profile to personalize and characterize the therapeutic approach.
The increase in the practice of running has encouraged a proliferation of studies evaluating the impact of this sport on health. A number of these studies have looked at the influence of endurance events on the immune system. After prolonged exercise, a systemic inflammatory syndrome sets in, with repercussions for the functioning of the immune system. The number of lymphocytes in the blood is reduced, the function of natural killer (NK) cells is impaired and secretory immunity is impaired. During this period of immunosuppression, often referred to as the 'open window', the host may be more susceptible to micro-organisms that bypass the first line of defence. The invetigators' hypothesis is therefore that ultratrailers are overexposed to the risk of infection due to immunodepression resulting from practising this sport. In order to support this hypothesis, the investigators would like to look at infectious complications in general and ear-nose and throat episodes (rhinitis, pharyngitis, laryngitis, etc.) in particular, which are the most common infections encountered in primary care, along with urinary tract infections.
The aim of this retrospective observational study is to evaluate the efficacy of antibiotic therapy with dalbavancin in patients presenting with infection on prosthetic devices. The main questions the study aims to answer are: What is the proportion of patients with early discontinuation of dalbavancin therapy? What are the reasons for early discontinuation of antibiotic treatment? What adverse events do patients report? The study is based on data collected as part of routine care practices.

Randomized quality improvement trial to improve the proportion of cases of community-acquired pneumonia (CAP) treated with no more than 5 days of antibiotics the proportion of cases of skin and soft tissue infections (SSTI) treated with no more than 7 days of antibiotics by primary care clinicians (PCC) within the Pediatric Physicians' Organization at Children's (PPOC), a state-wide pediatric primary care network. Interventions include education and feedback; clinical decision support (CDS) delivered at the point of care; and the combination of the two.
The primary purpose of this study is to understand the pharmacokinetics (PK) of single and multiple doses of cefiderocol in children from birth to less than 3 months of age with suspected or confirmed aerobic Gram-negative bacterial infections.
The Coronavirus 2019 (COVID-19) pandemic has resulted in at least four million infections in Norway. The vast majority of cases are diagnosed and followed up in the community, but some with extensive symptoms and large degree of reduced function are referred to regional Covid-clinics. In total this patient group is placing an enormous burden on the already over stretched health care services. As the pandemic subsides the emerging threat of long-term disability from COVID remains to be quantified. Brain fog and cognitive symptoms are common in long COVID in 30% of mild infections resulting in sick leave and loss of daily function, with women overrepresented among long COVID sufferers. The true prevalence and underlying mechanisms of long COVID remains to be quantified. Although vaccination prevents severe infection and death, we have little knowledge on how best to rehabilitate those who suffers from long COVID. Here we propose to develop knowledge on treatment interventions to counteract disability from long COVID and lessening the burden on health care services. We will conduct a study of where we compare a short group intervention with systematic personalised neurocognitive rehabilitation to document symptom alleviation. Our overarching goal is to develop effective programmes for this evolving disease to reduce the suffering for the patients, and thereby reducing costs for health services and society at large.
The goal of this type of study is to construct the continuous quality promotion project "ICU-NO CRBSI(Catheter-Related Bloodstream Infection , CRBSI)" based on improvement science, and to verify its effect in the prevention of central venous catheter-related bloodstream infection and continuous quality improvement in ICU ( Intensive Care Unit , ICU) through multi-center implementation and two rounds of improvement. The main question[s] it aims to answer are: What is the incidence of catheter-related bloodstream infection in the ICU of participating units? How compliant are health care providers in the ICU with evidence-based sensory control practices for the prevention of catheter-associated bloodstream infection? Participants will be provided with the hospital's routine CVC (Central Venous Catheter ,CVC) care practices and CVC quality improvement measures based on evidence-based guidelines What technical and cultural support is needed to implement quality and safety improvement measures?
