Filter by:There is an increasing focus on the need to optimise nutrition, lifestyle and metabolism of parents before and during pregnancy and of the infant after birth, but as yet there is limited understanding of the specific influences and of the underlying mechanisms. This study is a follow up of children from the NiPPeR trial of a nutritional drink enriched with micronutrients, myo-inositol and probiotics taken preconception and during pregnancy. In this setting we will examine the influence of parental nutrition, lifestyle and metabolism before and during pregnancy on child growth, development and well-being; ascertaining growth, adiposity, metabolism, neurobehavioural and health outcomes in the children, and characterising the underlying mechanisms. The data collected will allow identification of the contributions of parental and offspring characteristics, nutritional, lifestyle and medical factors, social and economic status, ethnicity, genetics, metabolism and microbes to promoting healthy growth, body composition and wellbeing in the children.
Study purpose: to explore the entire spectrum of proteomic and genomic changes (amongst others) involved in diseases and in healthy/control populations. The Study is designed to discover biomarkers, develop and validate diagnostic assays, instruments and therapeutics as well as other medical research. Specifically, researchers may analyze proteins, RNA, DNA copy number changes, including large and small (1,000-100,000 kb) scale rearrangements, transcription profiles, epigenetic modifications, sequence variation, and sequence in both diseased tissue and case-matched germline DNA from Subjects.
The goal of this individual patient data meta-analysis is to estimate the attributed and the associated health burden related to bloodstream infections, pneumonia, skin and soft tissue infections, surgical site infections and urinary tract infections, caused by target drug-resistant pathogens, in high income countries. The main question[s] it aims to answer are: - Are common infections caused by drug-resistant pathogens associated with an increased health burden, when compared with individuals with the same infection caused by a susceptible strain (attributed burden)? - Are common infections caused by drug-resistant pathogens associated with an increase health burden, when compared with individuals without the infection under study (associated burden)?
Acute head and neck infections cause significant pain and discomfort for patients and impact on their quality of life. Effective antibiotic and surgical treatments have been developed for these infections but they are still able to develop into life-threatening diseases such as meningitis and sepsis. The direct cause of acute head and neck infections is often unknown but it has been suggested that they are due to a disturbance of the normal bacterial growing in the mouth or are from dental origin. The most common microorganisms identified from these infections in published studies are a group of bacteria known as viridans group streptococci (VGS). There are over 30 individual species of bacteria in the viridans group and VGS are difficult to identify to the level of a single species because of their variability. There is a lack of species identification within the hospital setting and this project aims to gain a deeper understanding of the microorganisms causing acute head and neck infections, focusing on identification of individual species of VGS bacteria. The investigators will analyse bacterial DNA to determine which species have been identified and will also look at patient data and clinical outcomes (eg. length of hospital stay) to determine if the species causing the infection has any effect on patients.
Surgical site infection (SSI) is one of main complication in surgery. It usually occurs within 30 days post operation. The superficial SSI is an infection of skin and subcutaneous layer, clinically presented by pus oozing. Furthermore, seroma hematoma and wound dehiscence are also clinical signs of superficial SSI. Nowadays, there are studies which report methods reducing SSI by placing negative pressure drain within surgical wound. It can reduce serum in subcutaneous layer which is found in every surgical wound, especially in clean-contaminated and contaminated wound. Many studies show that placing negative pressure drainage within a surgical wound can reduce superficial SSI and decrease hospital length of stay by comparing with the control group. The objective in this study to compare the rate of SSI of clean-contaminated and contaminated surgical wounds between the patients whose wounds are placed with negative pressure drainage and patients who were not placed with negative pressure drainage.
This randomized controlled trial evaluates the efficacy of couples HIV testing and counseling retesting. Eligible couples previously enrolled in NCT05000866 are invited to participate. Those who do are randomized to either couples HIV testing and counseling (CHTC) retesting or an individual HIV testing control. Follow-ups occur 3 and 6 months post intervention.
The goal of this interventional study is to test if a discharge stewardship bundle is effective at reducing inappropriate antibiotic prescriptions at hospital discharge for children with the three common infections: community-acquired pneumonia (CAP), urinary tract infections (UTI), and skin/soft tissue infections (SSTI). The goals of this study are: - To develop, locally adapt, and implement a discharge stewardship intervention across four geographically diverse children's hospitals. - To measure the impact of the discharge stewardship intervention on antibiotic prescribing and patient outcome for three common pediatric infections. Families who are enrolled in the study will be asked to: - complete a one question wellness track on days 3, 7, and 21 after hospital discharge - complete a brief survey on days 7 and 21 after hospital discharge The study team will conduct interviews with the hospitalists at each of the four participating hospitals to create a "discharge stewardship" bundle. Once the bundle intervention is implemented, the hospitalists will be asked to follow prescribing guidelines for CAP, UTI, and SSTI. They will receive regular group-level feedback reports to show how well they follow the guidelines and motivate the hospitalists to follow the guidelines better.
The study will be a multicenter, hospital-based retrospective study. We plan to collect the clinical and laboratory data among all hospitalized ARTI cases in three hospitals in Wuhan from June 1, 2020 to May 31, 2023 and then analyze the epidemiological and clinical characteristics of RSV infection, clarify the gene types of epidemics under 5 years old children after the outbreak in Wuhan, China.
The use of titanium dental implants has become a common modern treatment to restore teeth. Although the success rate of dental implants is high, inflammation around the dental implant still occurs. The current study will investigate if the inflammation around the implant is due to bacterial infection, hypersensitivity or both. The goal of this cross-sectional study is to (1) Establish the levels of cytokines in peri-implant crevicular fluid associated with bacterial infection and hypersensitivity reaction; (2) Compare the levels of cytokines associated with hypersensitivity and bacterial infection between healthy implants and inflamed implants (peri-mucositis and peri-implantitis); (3) Determine whether the difference in the levels of cytokines, if they exist, reflects the clinical diagnosis of healthy implants and inflamed implants.
The 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.
