Colonisation Efficacy of a Probiotic Chewing Gum.
Microbial ColonizationTo evaluate the colonization efficacy (the ability of a probiotic bacteria to remain in the mouth) delivered in a chewing gum format. The chewing gum contains Streptococcus salivarius probiotic and the study is to be done in health adults.

The Role of the Gastrointestinal-associated Lymphoid Tissue in the Cure of HIV Infection
HIV InfectionThe objective of this study is to understand the effects of HIV cure strategies on the virus and immune cells that reside within the gastrointestinal tract. Subjects receiving therapies with the potential for HIV cure will undergo a colonoscopy to obtain gastrointestinal tissue for research assays. This study will test whether receiving these therapies will induce changes in the immune cells in the gastrointestinal tract and reduce the tissue-associated HIV viral levels.

The Effect of Catheter-Associated Infection Control Training
Infection Control TrainingThe goal of this type of study: clinical trial is to determine the effectiveness of educational practices on catheter-associated infection control measures on surgical nurses. The main question it aims to answer are: Is there a difference between the knowledge and attitude levels of surgical nurses receiving and not receiving catheter-related infection control training on preventing peripheral and central catheter-related bloodstream infections? Is there a difference between the knowledge and attitude levels of surgical nurses receiving and not receiving catheter-related infection control training to prevent catheter-related urinary tract infections? The main tasks that the participants will be asked to do will be explained and their consent will be obtained. The two research groups will be compared.

Probiotic Toothpaste for Microbial Colonization
Microbial ColonizationThe aim of this study is to evaluate the colonization efficacy of probiotic toothpastes in healthy adults

The Effect of ASTARTE™ on Recurrent Urinary Tract Infection
Recurrent Urinary Tract InfectionInvestigate the effect of dietary supplements/probiotic ASTARTE™ ( L. crispatus, L. rhamnosus, L. jensenii, L. gasseri) on the microbiome composition in the intestine and vagina and thereby a reduction of risk factors for the development of rUTI during 6 months of intervention in women aged 18-40 years. This is measured by the incidence of symptomatic UTI.

Antiviral Activity of Oral Probiotics
Lower Respiratory Tract InfectionUpper Respiratory Tract InfectionThe aim of this study is to test saliva samples obtained from healthy human participants for anti-viral activity after they have consumed S. salivarius probiotic in a powder format.

Skin Preparation for Elective Foot and Ankle Surgery
Microbial ColonizationFoot and Ankle DisordersSurgical site infections (SSIs) make about 31% of all nosocomial infections and they are the most common hospital-acquired infection. For foot and ankle elective interventions, SSI rate is reported between 0.4% and 3.6%. This study will investigate the effectiveness of skin cleaning with isopropyl alcohol and scrubbing with chlorhexidine soap before standard skin preparation in reducing microbial load and surgical site infections for elective foot and ankle surgeries. Current standard of care includes skin preparation with iodine or chlorhexidine solution prior to sterile draping and the start of surgery. Standard of care will be applied to all patients. The use of an additional "pre-scrub" with isopropyl alcohol and scrubbing with chlorhexidine soap will be applied to the experimental group. The control group will receive only the standard of care skin preparation with iodine or chlorhexidine solution prior to draping.

Temocillin Pharmacokinetics in Paediatrics
InfectionLiver Dysfunction1 moreTemocillin (6-methoxy-ticarcillin) is a beta-lactam antibiotic with exceptional resistance to most beta-lactamases. In this context, it is now increasingly used as carbapenem-sparing antibiotic in patients with suspected infection by Enterobactreriaceae suspected to produce extended-spectrum beta-lactamases. Little is known about dosing and elimination of temocillin in children. While available literature of temocillin use in paediatrics refers mainly to its clinical efficacy in the treatment of urinary tract infections, the drug is also used for the treatment of suspicion of cholangitis in cirrhotic paediatric patients, and as antibiotic prophylaxis following an hepatic transplant in children (both off-label indications). There is, therefore, a pressing need to explore the pharmacokinetics and pharmacodynamics of temocillin in the paediatric population, in order to provide clear guidance on an appropriate dosing regimen. The study objectives are: (1) characterisation of the pharmacokinetics (PK) of temocillin in 3 paediatric populations, (2) proposal and development of a dosing schedule that can ensure therapeutic concentrations (40% ƒT > MIC) and optimize treatment chances of success, and (3) characterization of MICs of microbiological strains (when available) to temocillin.

Plasma Protein Binding and PK/PD of Total and Unbound Temocillin Non-ICU Patients
PharmacokineticsAntibacterial Agents5 moreMultidrug resistance towards Gram-negative pathogens makes essential the re-examination of older compounds. Temocillin is a penicillin originally marketed in the 1980s but then largely abandoned. It, however, shows a marked ß-lactamase stability (including most classical and extended-spectrum TEM, SHV, CTX-M enzymes and AmpC ß-lactamase). Temocillin is approved for the treatment of bacterial infections of the chest, the lungs, the kidney, the bladder, as well as bacterial infections of the bloodstream and wound infections. Temocillin efficacy depends primarily from the time interval during which the unbound plasma concentration remains above the minimal inhibitory concentration (MIC) of the antibiotic against the target organism(s). Unfortunately, no comprehensive pharmacokinetic data are available in non-critically-ill patients. The primary objective of the study is characterize the pharmacokinetics of total and unbound temocillin in non-ICU patients, and, on this basis, to propose optimized dosage regimens in this population. The secondary objectives are (i) to look for possible correlations between the plasma protein profile and the unbound temocillin concentrations; (ii) to investigate the impact of the level and nature of circulating plasma proteins on the unbound temocillin concentration. The study will be non-randomized, uncontrolled, prospective, open label, interventional, and monocentric. It will include a population pharmacokinetic-pharmacodynamic analysis of the data obtained. The study will enroll patients ≥ 18 years in need of a treatment with temocillin for (i) complicated urinary tract infection and pyelonephritis (associated or not with bacteremia), or (ii) lower respiratory tract infection, or (iii) abdominal infection, and requiring ≥ 4 days of hospitalization. Blood samples will be obtained at day 0 (control) and after 2 and 4 days of drug treatment (full pharmacokinetic evaluation over 8 to 12 h post-administration). Total and unbound temocillin concentrations in plasma will be quantified by a validated analytical method. A population pharmacokinetic/pharmacodynamics model of plasma total and unbound concentrations of temocillin will be obtained by Bayesian algorithms using Pmetrics software, driven by the predicted plasma total and unbound concentration. The model will be used to assess the probability of target attainment of temocillin.
