Filter by:This study will test a new drug (MAM01) to find which doses are safe and could help prevent people from getting malaria. The study will take place in parts of Africa where malaria is common. Parts A and B of the study will first test single doses of MAM01 in healthy adults, then after safety review, in older children, and then after additional safety review, in infants. Part C will then test single doses of MAM01 in children and infants who have a medical problem that could put them at greater risk if they get malaria.
The objective of this study is to assess the pharmacokinetics, immunogenicity, safety, and tolerability, of subcutaneous formulation of ravagalimab in a pre-filled syringe in healthy adult participants.
This is a Phase 1, single-center, open-label, single-arm, dose-escalation positron emission tomography study to assess the safety and tolerability, immunogenicity, Pharmacokinetics, dosimetry, and biodistribution after GEH200521 (18F) Injection is co-administered with GEH200520 Injection in healthy volunteers. The estimated study duration for each subject is approximately 28 days. The primary study objective is to evaluate the safety and tolerability of the IMPs, the selected mass doses of GEH200520 Injection co-administered with a fixed dose of GEH200521 (18F) Injection.
Background: Measuring what people eat is a challenge in nutrition research. Traditional methods, like food diaries, rely on self-reporting of individuals, and suffer from poor accuracy and recall bias. Aims: This project aims to identify physiological biomarkers related to food and energy intake, which may be used to develop an objective tool to estimate individuals' food intake in future. Eating behaviours are accompanied by significant physiological changes such as skin temperature, blood oxygen saturation, pulse rate etc. The investigators intend to investigate whether monitoring these physiological changes can help us estimate eating behaviour, such as meal size, eating speed, and duration of meals. Study design: Ten healthy adults will be invited for two study visits at NIHR Imperial Clinical Research Facility. Each visit will last for approximately 2 hr. They will consume a high- and low-calorie meal designed by nutritional researchers in a randomised order. During eating events, the investigators will track their physiological changes via a bedside monitor and wearable sensors. Blood samples will be taken from participants to measure their glycaemic response. Associations between energy load, glycaemic response, and physiological changes will be investigated. Our findings may promote an accelerated development of a wearable tool for dietary assessment in future.
The goal of this bioequivalence of two formulations of generic apixaban 5 mg film-coated tablets. Single-dose under fasting conditions and pharmacokinetics will be characterized for a total of 28 healthy adult human subjects. Twenty-eight (28) subjects will be randomly assigned to receive either generic apixaban 5 mg film-coated tablets (1 x 5 mg; Test) or ELIQUIS (1 x 5 mg; Reference) in Period 1 and after the washout period they will receive the other formulation as a crossover fashion in Period 2.
The purpose of the study is to assess the relative bioavailability of two Magne-B6 preparations, in fasting conditions.
Transcutaneous electrical nerve stimulation (TENS) is a non-invasive modality that utilizes electrical currents to modulate pain in populations with acute and chronic pain. TENS has been demonstrated to produce hypoalgesic effects in postoperative pain, fibromyalgia, knee osteoarthritis, and healthy subjects. Transcutaneous auricular vagus nerve stimulation (TaVNS) is a non-invasive modality that modulates the vagus nerve by stimulating its auricular branches. The effects of the combination of TENS and TaVNS on producing an analgesic response have not been studied. Considering that TENS and TaVNS both stimulate similar analgesic pathways but through different means of activation, the investigators can hypothesize that a combination of both methods can produce a more pronounced analgesic response. Therefore, the objective of this study is to assess the hypoalgesic effect of a combination of TENS and TaVNS in pain-free subjects. The study will be a simple crossover design conducted at the University of Hartford. Subjects will be recruited from the University of Hartford population via oral communication, digital flyers, and posters on campus. Thirty participants will undergo two sessions in a crossover manner with one week in between. During one session, the participants will receive TENS with active TaVNS and the other session will be a placebo procedure (TENS with placebo TaVNS). The order of these sessions will be randomized. Importantly, the pressure pain threshold (PPT) and heat pain threshold (HPT) assessors will be blinded to the treatment category. For active TaVNS, a frequency of 25 Hz will be applied with a pulse duration of 200 µs. For placebo TaVNS, the intensity will be increased to a sensory level and then decreased to 0 mA. High frequency TENS of 100Hz will be applied in both sessions, with a pulse duration of 200 µsec, asymmetrical biphasic square waveform, and intensity of maximal tolerance without pain. TENS and TaVNS will be turned on for 30 minutes after a baseline measurement of outcomes. TENS and TaVNS will then be turned off, but the electrodes will remain on until completion of post-treatment assessment. Pressure pain threshold, heat pain threshold, blood pressure, oxygen saturation and heart rate will be tested 4 times: Once pre-intervention, once during intervention, once immediately after the intervention and once 15 minutes post-intervention.

Drug-drug interaction study of Biktarvy and Bemnifosbuvir/Ruzasvir
No patient data is involved in the study. This study is designed to understand better how Emergency Care Advanced Clinical Practitioners (EC-ACPs) work in emergency departments (EDs). The main research question is: 1) What is the EC-ACP's perception of assimilation into emergency care teams, what tensions are created due to the role, and what system adaptations are required to facilitate integration? With secondary aims : 1. What are the common organisational factors that affect the implementation of the EC-ACP workforce, and what recommendations can be made to improve Trust-wide implementation? 2. How are EC-ACPs deployed in two contrasting emergency departments, what differences can be identified in their Work-As-Done (WAD), and how does this compare to the Work-As-Imagined (WAI) of the role? Participants will all be staff members who work in the hospital. Patient data is not being collected or processed. This is a mixed-method study using two approaches to collect data: 1. Observation of the EC-ACPs at work - noting how they interact with colleagues and how they are deployed in the ED. 2. Interviews with various staff who work with the EC-ACPs clinically or in various managerial or director roles. Background In the UK, a health care role has been developed called Advanced Clinical Practitioners (ACPs). ACPs work in various clinical settings, but this study focuses on those in Emergency Care. While non-medical practitioners have worked in Emergency Departments (EDs) for over 20 years, the ACP role is relatively new. Most ACPs in ED are from a nursing or paramedical background, but they can also be from other allied health professions like physiotherapy. After the base qualification, ACPs undertake a three-year master's degree with clinical portfolios. Once qualified, the goal is to create clinicians who work alongside doctors, seeing, treating, and discharging patients. Unlike previous practitioner roles, EC-ACPs treat the whole spectrum of ED patients, from minor injuries and illnesses to the sickest patients needing the highest level of care. These roles were heavily supported by local and political desires to create blended workforces to meet increasing patient demands. The problem with implementing ACP roles is that initially, little consultation was held with stakeholders in EDs. This has resulted in various trade-offs. For example, trainee doctors often feel displaced by trainee ACPs seeking to learn the same or similar skills. Previous research on advanced roles in ED has focused on direct clinical comparisons between doctors and practitioners. Researchers have investigated which professional (doctors vs. nurse practitioners) triages patients quickest or who is more accurate at interpreting X-rays. There are several problems with these approaches. The first is that they can create a professional rivalry. The second problem is that these approaches oversimplify what is a more complex system of care.
