Filter by: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.
This is a prospective, observational study of patients undergoing open GI surgery. At the time of operation, samples will be collected from the incision site and GI tract. The study will follow patients up to 30 days postoperatively, monitoring for signs of SSI. Samples will be taken from all patients who develop SSI. Sequencing will be performed on a subset of samples based on our specific aims. - Aim 1: conduct a case-control study of patients with SSI and age-, sex-, diagnosis-, and wound class-matched control patients without SSI, comparing microbiome alpha diversity and community composition with 16S RNA sequencing to determine the association with SSI. - Aim 2: identify the strain of bacteria isolated from SSIs using shotgun metagenomic sequencing and determine whether the specific strain was present in the skin and gut at the time of operation.
The goal of this study is to improve the way urinary tract infections (UTIs) are tested for antibiotic resistance. The main questions it aims to answer are: - Can the investigators use a method called Bayesian causal inference to create or check clinical prediction models that help predict if certain antibiotics will work for a urinary infection, using patient information from the National Health Service (NHS)? - Can this new ADAPT-AST method, which uses data and a smarter approach, do a better job of testing for urinary infection than the old methods? Will it help doctors make quicker decisions and save resources by being more efficient? Participants in this study will not be receiving treatments. The study will involve: Using statistical methods to predict UTI test results based on patient data. Evaluating whether this new approach can provide doctors with more timely and useful information for treating UTIs. Assessing whether it can help save money and resources in the lab and pharmacy.
Streptococcus pyogenes, commonly referred to as Group A Streptococcus (GAS), has the ability to induce a diverse range of illnesses. In several European countries and the United States, a notable surge in invasive GAS (iGAS) infections has been documented since mid-2022. This sharp increase contrasts with the gradual rise in iGAS incidence observed among children over the past three decades. As demonstrated for several viral infections, the recent upturn in iGAS infections is potentially linked to the relaxation of mitigation measures implemented during the COVID-19 pandemic, such as face mask usage and school closures. Since November 2022, concerns have been raised by French public health authorities regarding the rise in levels of iGAS infections, and an unexpected increase in pediatric severe GAS infections was reported in a French single-center study. However, this study ended in December 2022 and could only explore short-term trends. The Necker - Enfants malades Hospital in Paris, France, represents an excellent opportunity to examine the impact of the COVID-19 pandemic and the associated non-pharmaceutical interventions on the incidence of severe GAS infections, during, and after the pandemic. This study aims to investigate trends of severe GAS infection incidence in children in the Paris area over the course of the COVID-19 pandemic.
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.
Lower respiratory tract infections (LRTIs) are one of the most common reasons for consultation in Primary Care centres. Differentiating between viral and bacterial aetiologies can be challenging, leading to inappropriate antibiotic prescribing. Lung ultrasound (LUS), an imaging test that gained particular relevance since the beginning of the SARS-CoV-2 pandemic, offers several advantages over the classic chest X-ray in detecting and monitoring LRTIs, especially when pleural involvement exists. This study aims to correlate LUS findings with capillary blood C-Reactive Protein (CRP) values in patients with LRTIs, evaluating LUS as a diagnostic tool and its impact on therapeutic decisions. The descriptive observational study, conducted from January 2024 to December 2026 in Lleida, will include LRTI patients attending Primary Care centres. By validating LUS as a rapid and non-invasive diagnostic tool, unnecessary antibiotic prescriptions can be reduced, promoting LUS as a complementary test in Primary Care consultations. This will facilitate appropriate diagnosis and treatment decisions for patients with LRTIs, enhancing the overall management of respiratory infections.
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.
