Anti-Bacterial Agents

This study is non-inferiority trial design. This study aimed to investigate the effect of prophylactic oral antibiotics on preventing cholangitis in biliary atresia (BA) patients after Kasai portoenterostomy (KP) by comparing the cholangitis rate in BA patients who received prophylactic oral antibiotics and those who did not. The patients were followed up for 2 years after KP.

Cat bites are puncture wounds that have the potential to seed bacteria deep within the joint capsule, periosteum, and bone. The hand is the most common site of bite injuries. Pasteurella multocida is the is the most common organism isolated from the mouths of cats that can cause infections after a bite. Prophylactic antibiotics are often recommended with amoxicillin-clavulanate for 3-5 days to decrease the incidence of developing an infection. However, only one randomized controlled clinical trial consisting of 12 patients has been performed to justify this course of treatment, raising the possibility that the use of antibiotics could be reduced or even eliminated. Investigators will compare different durations of prophylactic antibiotics and a placebo control for cat bites to the hand/forearm presenting to the Emergency Department, Urgent Care, Plastic Surgery Clinic using a randomized, controlled, double-blind clinical trial. Participants presenting to the University of Missouri Hospital Emergency Department, Missouri University (MU) Healthcare Urgent Care, Plastic Surgery Clinic over the next year will be offered the chance to enroll if they meet the inclusion/exclusion criteria. For inclusion, participants will be \>18 years of age, have cat bites to the hand or distal to elbow, and present within 24 hours of the cat bite injury. Participants must not present with active local or systemic infections, have received antibiotics within the past 30 days, or be immunocompromised (primary and secondary immunodeficiencies). Participants will be randomized to one of three treatment arms (placebo; amoxicillin-clavulanate 1 day; amoxicillin-clavulanate 5 days). Outcomes are the development of an infection at the location of the cat bite and/or systemic infection, adverse effects of interventions, disability assessed by Quick Disabilities of Arm, Shoulder and Hand (QuickDASH) scores, and quality of life (QOL) assessed by HAND Questionnaire (HAND-Q) scores. Infection will be assessed at day 0, day 2, day 7+/-2, day 14+/-2, and day 30+/-2 by vital signs, laboratory values, physical examination and with an infrared and digital camera. All measures will be within the standard of care, apart from the infrared camera, QuickDASH, and HAND-Q scores. The anatomic locations of cat bites to the hand/forearm will be assessed for correlations with infections.

The goal of this interrupted time-series analysis is to evaluate the impact of the de-implementation of urine dipsticks as a diagnostic tool for urinary tract infections (UTIs) in hospitalized patients in the North Denmark Region. The main question it aims to answer is: How does de-implementation of urine dipsticks affect the diagnosis and management of UTIs and related disorders? Specifically, does it change the following parameters: * Number and severity of UTI infections (lower and upper UTI, non-severe and severe) * Antibiotic prescription (overall, antibiotic classes, administration routes, duration, dosages) * Number of urine cultures and number of positive urine cultures * Risks of admission to intensive care units and 30-day mortality * Risk of drug toxicity * Length of hospital stay * Risk of admission to intensive care unit * 30-day risk of readmission after discharge * 6-month risks of Clostridioides difficile enterocolitis and de novo antimicrobial resistance in cultures obtained during routine clinical care. Researchers hypothesize that de-implementing urine dipsticks will lead to a reduced frequency of diagnosed cystitis, reduced antibiotic use, and fewer urine cultures without negatively affecting patient mortality or readmission risk. Researchers will compare the outcomes before and after the discontinuation of urine dipsticks across hospitals in the North Denmark Region. Furthermore, results will be compared to another Danish administrative healthcare region where dipsticks are still in use as well as urine culture data from the primary sector in the North Denmark Region. Since this is a registry-based observational study utilizing data from the electronic patient record system in the North Denmark Region, no direct contact will be made with participants.

The FLORA-ACS study aims to evaluate the relationship between dysbiosis and high platelet reactivity during treatment with ticagrelor in patients with a history of acute coronary syndromes and investigate the use of rifaximin to eliminate dysbiosis and thus provide effective antiplatelet treatment.

This study looks at how different antibiotic treatments affect patients in intensive care who have pneumonia caused by the bacteria Stenotrophomonas maltophilia. It compares using one antibiotic versus two antibiotics, and treatment lengths of 7 days versus 14 days, to see which approach helps patients survive better. The study also examines how resistant the bacteria are to antibiotics and how often the pneumonia comes back.

This is a multicenter prospective cohort study in which patients were evaluated by inclusion and exclusion criteria before phase II revision surgery. Eligible patients will be included in this study after signing the informed consent form. After the second stage revision, according to the patient's symptoms and examination results, the attending physician used a reasonable antibiotic treatment scheme (including intravenous and oral medication). All patients voluntarily participated in the study and signed informed consent. During the treatment period, all prospective patients underwent clinical evaluation at the time points of 1, 3, 6, 12, 18 and 24 months after the start of antibiotic treatment after phase II revision. The infection control rate of patients was evaluated by follow-up at least 2 years after operation, so as to analyze the effect of antibiotic treatment course after two-stage revision of periprosthetic joint infection.
