Filter by:Infection with Streptococcus pneumoniae (the pneumococcus) is the leading cause of pneumonia, bacterial meningitis and bacteraemia worldwide in the very young and the elderly. Although pneumococcal vaccines exist, they do not provide complete protection and new strategies to combat this pathogen are urgently needed. Asymptomatic infection of S. pneumoniae in the human nasopharynx precedes the development of pneumococcal disease. Previously, an Experimental Human Pneumococcal Carriage (EHPC) model has been developed at the Liverpool School of Tropical Medicine (LSTM). The current study entails to establish this model in healthy adults living in the Netherlands using the inoculation dose currently used at LSTM. Healthy adult participants (M/F) will be inoculated intranasally with strain BHN418, a penicillin sensitive serotype 6B strain of S. pneumoniae that was previously isolated from a healthy carrier. Following inoculation, participants will be monitored and blood and nasal samples will be collected over a period of 28 ± 3 days. Participants will receive a course of amoxicillin to eradicate infection on or shortly after the last visit at day 28 ± 3, unless S. pneumoniae is not detected on both day 14 and 28 ± 3 post-inoculation.
Having bacteria in the blood can be very dangerous. This is called bacteraemia (or bacteremia) or bloodstream infection. It can lead to problems across the whole body, which is what happens in sepsis. Bacteria called Staphylococcus aureus (S. aureus) cause one kind of bacteraemia. Up to a third of people with this condition die within three months, even with antibiotics. One reason for such severe problems is that the bacteria can spread almost anywhere in the body, and hide in places where they are very hard to find. When people with S. aureus bacteraemia come into hospital and have had antibiotics, doctors sometimes cannot tell if they still have an infection source (called a 'focus') hiding in their body. The focus can be like an abscess and may need removing or the pus draining out. A focus might be obvious, if there is pain or swelling, or it might be hidden and deep. If these 'foci' can be found, then doctors can treat them and this helps to cure patients. To improve survival for patients with these life-threatening infections, it is vital that doctors find the focus of S. aureus bacteraemia as quickly as possible. However, the research team do not know the best way to do this. Most patients with S. aureus bacteraemia have a chest X-ray and a scan of the heart valves. Patients may go to the scanning department lots of times while doctors try to work out where these foci are. This is uncomfortable and takes a lot of time. In about 1 in 5 cases the doctors still cannot find the focus. This is very worrying for patients, their relatives and doctors. This study has been designed by researchers, doctors and patient advocates. It aims to work out if fewer patients may die when a specific type of scan called a 'PET/CT' is done quickly, because it finds more foci. To do this the team plan to do a clinical trial in patients with S. aureus bacteraemia. Half of the patients will receive the usual tests that patients currently get and the other half will receive an extra scan as soon as possible. The patients will be chosen randomly (like the flip of a coin) to go into one of the 2 groups. A year into the trial, an independent committee will check the results to make sure the extra scan is finding more foci. If this is the case, the trial will carry on. At the end of the study, we will share the results globally. The findings are expected to change the way this dangerous condition is managed, so patients do better.
People of all ages are affected by intestinal parasitic infections(IPIs) ; however, children are the most commonly affected, which is linked to their poor hygienic practices, and weak immune status. In children, IPIs are associated with malabsorption, weight loss, anemia, poor growth rate, learning difficulties, mental retardation and intellectual problems . The difficulty of diagnosis is the main problem in the control of intestinal parasitic infections. The choice of a particular technique is usually influenced by affordability, simplicity, cost, sensitivity in addition to the level of technical skills involved. Microscopic examination remains the cornerstone of parasitological diagnosis which is time consuming and requires an experienced observer to identify the organism. Formalin-ether sedimentation technique is commonly used in laboratories owing to its ability to isolate a large variety of parasites. However, it's a labor intensive procedure and is usually associated with hazards of using the inflammable lipid solvents. The drawbacks of the previous techniques have encouraged the development of commercial products such as Feconomics which is a new ready to use kit for concentration of stool samples in parasitological diagnosis. The aim of the study is : evaluation of the efficacy of Feconomics technique in comparison to traditional techniques i.e., direct smear and formalin ethyl acetate sedimentation technique for the diagnosis of intestinal parasites in school children.
Purpose: To test the feasibility, acceptability of the IA intervention (four telenovela episodes), assessment of the mechanisms of action (self-efficacy, narrative engagement, and emotional elicitation) and conduct a randomized controlled pilot study to examine the change in primary outcomes (condom use, HIV testing, Pre-exposure Prophylaxis (PrEP) awareness and use) and secondary outcomes (Substance abuse (SA), intimate partner violence (IPV), and depression comparing 33 intervention- and 33 control Latinas at baseline (T1, pre-intervention), T2 (immediately post-intervention, 1 month) and T3 (3 months after the end of the intervention, with no intervening contact with study staff). Participants: 66 Latinas ages 18-44 years who report sexual activity with a man in the last 6 months, have internet access from any device, and reside in NC. Procedures (methods): Participants will be asked to: (1) receive an orientation about the use of the Infección de Amor (IA) telenovela website and access the telenovela website once a week for 4 weeks to watch a telenovela episode and answer some questions about the episode (half hour each week, 2 in total), (2) attend to a one hour-meeting with the research team to complete a baseline survey, (3) complete a survey (on their own) one-month after the baseline survey, and (4) complete another survey (on their own) 4-months after the baseline survey. Participants will complete a structured survey in the first meeting (baseline survey) with a member of the research team and then they will complete the follow-up surveys (1-month and 4-months after baseline) on their own. Participants can request help to complete these surveys with the help of the research team (online using Zoom or face to face if needed). The moment that participants will access the IA intervention will depend on the group to be assigned by the research team (intervention or control group).
In the proposed study, we will apply Prevena on the surgical wound right after closure of the wound in the operating theater. Prevena will be used for 7 days, unless there is ongoing infection or much wound drainage that requires debridement. Most periprosthetic joint infections are from hematogenous origin. Hence, it is considered clean wound unless there is a discharging sinus.
The objective of this study is to evaluate the efficacy of Sasch1, a novel anti-infective eyedrop, in the treatment of acute infectious conjunctivitis.
Surgical site infection (SSI) is one of the most common postoperative complications in surgery, with high morbidity. In the tertiary-center that the investigators evaluated they had a significant rate of surgical site infection. Because of that the investigators created a care bundle of measures in order to improve the outcomes.
Data regarding optimal treatment for extended-spectrum beta-lactamase (ESBL) producing Enterobacterales bloodstream infection are lacking. Observational studies show conflicting results when comparing treatment with combination beta-lactam-beta-lactamase inhibitor and carbapenems. The investigators aim to evaluate the effect of definitive treatment with meropenem vs. piperacillin-tazobactam on the outcome of patients with bacteremia due to cephalosporin-non-susceptible Enterobacteriaceae. The investigators hypothesize that piperacillin-tazobactam is non-inferior to meropenem.
Lower respiratory tract infection(LRTI) is a prevalent disease that threatens the health of older people worldwide. Anemia is also a common disorder in the elderly, and its prevalence increases significantly with age. Most factors that contribute to the development of anemia are improvable. Therefore, we investigated whether anemia was a risk factor for LRTI-caused readmission and death in the elderly occurring within 1 year of discharge from the hospital.
The treatment outcome of Mycobacterium abscessus infection in acquired interferon-gamma autoantibody syndrome has not been well studied. Investigators will perform a retrospective and prospective cohort study to determine the treatment outcome of Mycobacterium abscessus infection in patients with acquired interferon-gamma autoantibody syndrome compared with the infection in patients with chronic lung disease which is known to be the most common group of infection and have high rates of treatment failure. Investigators hypothesized that Mycobacterium abscessus infection in acquired interferon-gamma autoantibody syndrome has better outcome than infection in chronic lung disease.
