Filter by:Clostridioides difficile infection (CDI) is the leading cause of nosocomial diarrhea in Europe, with over 120,000 cases and almost 3,700 deaths per year. This infection is characterized by a high risk of recurrence after cure, ranging from almost 20% after a first episode to over 60% after 2 recurrences, or in the case of specific risk factors. Currently, first-line treatment of CDI is based on oral antibiotics such as fidaxomicin or vancomycin. These antibiotic treatments, which are effective in 89% and 86% of first-episode cases respectively, do not correct the microbiological imbalance underlying the onset of CDI and may, on the contrary, encourage recurrence by contributing to the maintenance of a deleterious change in the microbiota (dysbiosis) through the elimination of bacteria other than C. difficile, due to their spectrum of activity. In a number of patients, this ecological imbalance can no longer be restored after antibiotic treatment, leading to multiple recurrences of CDI. In this context, fecal microbiota transplantation (FMT) has been validated for over 10 years for the prevention of recurrence in multi-recurrent CDI. The principle of FMT is based on the use of a pharmaceutical preparation made from the stool of a healthy donor, administered within the digestive tract of a patient for therapeutic purposes. Currently, in the case of multiple recurrences, it is the recommended first-line treatment (from 2 recurrences) and the most effective, with a clinical efficacy preventing recurrence of CDI in 69% to 89% of cases at 8 weeks post-treatment, with a good safety profile. Among the microbial factors promoting CDI, the loss of the bacterial species Faecalibacterium prausnitzii constitutes a specific therapeutic target. F. prausnitzii is a commensal bacterium of the human gut, making up nearly 5% of the fecal microbiota, and has been shown to be associated with an individual's state of health. A drop in its relative abundance is associated with an increased risk of numerous diseases, such as Crohn's disease and colorectal cancer. In CDI, F prausnitzii is greatly diminished. Moreover, low abundance of F. prausnitzii is predictive of C. difficile recurrence. Its abundance in stools is increased after FMT and is also predictive of response to treatment. From a pathophysiological point of view, one of the preventive effects of F. prausnitzii on recurrence would be mediated by its ability to hydrolyze the bile acids involved in the germination of C. difficile spores. The aim of this Phase I/II trial is to assess the efficacy and safety of oral administration of EXL01, a single isolated unmodified strain of F. prausnitzii, in preventing CDI recurrence in high-risk patients at W8. The study will be conducted in 2 parts. The phase I (Part A) is planned to include 6 patients. The phase II (Part B) will include 50 patients in two arms (25 patients respectively in the placebo and EXL01 arm).
Helicobacter pylori infection is a major cause of morbidity and mortality worldwide. More than 50% of the global population is estimated to be infected. In 2015, there were approximately 4.4 billion individuals with H pylori infection worldwide. In Pakistan the prevalence of H. pylori infection, highest (63%) in middle age (41-60 years) group while lowest (33%) in teens and pre-teens (<20 years) group. In young age (20-40) and old age (>60 years) groups, the prevalence of H. pylori was 55% and 60% respectively. In conventional system of medicine H. pylori infection is treated by triple regimen antibiotic therapy that are amoxicillin, clarithromycin and metronidazole along with acid reducing proton pump inhibitor. Due to recurrence of infection this therapy is repeated multiple times resulting in drug resistance and long term side effects. These side effects & a long term impact of H. pylori in patient general health necessitates development of a safe and long term effective therapy.

Considering the relatively high incidence of surgical site infection (SSI) in colorectal surgery, this trial will compare rates of SSI in patients undergoing colorectal resections followed by surgical wound irrigation with povidone-iodine versus the group of patients undergoing surgical wound irrigation with saline solution. The trial will be conducted in a large university hospital in Southern Brazil.
The goal of this observational study is to learn about vaginal microbial characteristics in the patients under in vitro fertilization treatment. The study aims to address the following questions: (1) Is there any difference in microbial composition between the pregnancy and non-pregnancy groups? (2) Is there any differences in specific bacterial species between the two groups? (3) What are the favorable or unfavorable profiles of vaginal microbiota associated with achieving pregnancy? Patients will be asked to complete a questionnaire regarding their basic characteristics, and vaginal secretions will be collected via vaginal swab during frozen-blastocyst transfer procedures. The study will compare vaginal microbiota between pregnant and non-pregnant patients to assess its potential influence on clinical outcomes.
To explore the analysis of factors causing indwelling urinary catheter-related infections in ICU patients and their nursing strategies, and to provide reference for clinical nursing work. 291 patients with indwelling urinary catheters in the second area of ICU of our hospital from January 1, 2023 to September 30, 2023 were selected as research subjects. They were divided into infection group and non-infection group according to the presence or absence of urinary tract infection. Non-infection group The first group consisted of patients without urinary tract infection (278 cases), and the infection group consisted of patients with urinary tract infection (13 cases). A retrospective analysis method was used to analyze the causes of catheter-related urinary tract infection and the infecting bacteria of the two groups of patients. A single factor analysis was performed on various factors and other related factors, and corresponding nursing strategies were summarized and proposed.
In the US, if you get an infection in your artificial knee joint that doesn't heal with antibiotics alone, the standard treatment is a two-stage revision of the artificial knee. In the first stage, your surgeon will remove your artificial knee and clean out the area around the knee. They will then place an antibiotic spacer. An antibiotic spacer is a type of artificial joint that will release antibiotics in to the knee space continuously over time. The spacer allows only very basic function of the knee. You may need to use crutches or a walker while the antibiotic spacer is in place. After surgery to place the antibiotic spacer, your surgeon may prescribe a course of antibiotics as well. Because the antibiotic spacer is not as durable as a regular artificial joint, after the infection is gone, another surgery is required to take the spacer out and put a new artificial knee joint in. There is another way for artificial joint infections to be treated. This is a one-stage revision. In this treatment, the surgeon will remove your artificial knee and clean out the area around the knee. Then they will place a new artificial knee in using a special kind of cement that contains antibiotics. The cement will release antibiotics in to the knee space continuously over time (your surgeon may prescribe a course of antibiotics as well). The new artificial joint with antibiotic cement will function almost the same as your original artificial knee. This means that while the infection is healing you will be able to do most of your regular daily activities. However, the antibiotic cement is not as durable as what is normally used to implant an artificial knee. The artificial knee with the antibiotic cement may need to be replaced with a regular artificial knee. When replacement will need to be done is dependent on your weight, bone strength and activity level, among other things. When it is time to replace the antibiotic cement artificial knee, you will have another surgery where the surgeon will take the antibiotic cement artificial knee and but a new artificial knee joint in. We know that both the one- and two-stage revision work equally well to heal the infection, but we don't know which patients prefer or which provides better function after many years. This study will randomly assign patients to receive either a one-stage or two-stage revision and then follow them for 5 years to ask them about pain, function, and satisfaction.
These studies offer valuable insights into the potential development of KGR as a novel herbal-based preventive and therapeutic strategy against COVID-19.
