Filter by:Viral respiratory tract infections (VRTI) are among the most common human illnesses, impacting billions globally. There is an unmet need to identify novel ways to detect, treat and prevent their spread. New wearable devices could address this need, using special biosensors worn by patients. This is a single centre, controlled, before and after, longitudinal, clinical trial. Participants will receive FluMist, a live attenuated influenza vaccine, which will act as a proxy to a viral respiratory tract infection and create a very minor response to the immune system. Vital signs and activity levels will be monitored continuously using wearable biosensors for 7 days prior to and 7 days following, along with symptom tracking and blood tests to measure immune responses. Artificial intelligence (AI) and machine learning (ML) algorithms will be used to analyse the data. AI and ML will identify subtle changes in vital signs and activity levels from the immune response to respiratory viruses. These data will help develop future methods to address important public health questions related to respiratory virus detection, containment and management. The purpose of this study is to explore whether wearable sensors can detect, track the progress and recovery from viral respiratory tract infection.
Severe Community-acquired pneumonia (SCAP) is a leading global infectious cause of intensive care unit (ICU) admission (approximately 20%-30%), and the primary reason of mortality and morbidity in immunocompromised patients. There is a global increase of patients with distinct immunocompromised conditions due to the advance of cancer treatment, increasing biologics, and immunosuppressants for autoimmune diseases and growing organ transplant recipients, and it has been estimated that patients with immunocompromised conditions account for approximately 35% of all intensive care unit (ICU) admissions. Immunocompromised patients with SCAP have more factors to complicate with sepsis, respiratory failure, acute respiratory distress syndrome, and the mortality rate can be up to 50%. With the aim to apply early accurate antimicrobial therapy to improve clinical prognosis of SCAP patients with immunocompromised conditions, timely identification of pathogen is particularly important. Conventional microbiological diagnostic methods such as standard microbiologic cultures, microscopy, polymerase chain reaction (PCR), respiratory virus multiplex PCR, as well as pathogen-specific antigens and antibody assays, are currently commonly used to detect pathogens, although they have various limitations. However, conventional antimicrobial therapy depends on the results of conventional diagnostic methods, which may delay timely accurate antimicrobial therapy at the initial stage, and the mortality of immunocompromised patients with SCAP may be increased. Metagenomic next-generation sequencing (mNGS), which can determine pathogens more quickly (usually within 24h) and accurately comparing with conventional diagnostic methods by analyzing cell-free nucleic acid fragments of pathogens using appropriate lower respiratory tract (LRT) specimen, is increasingly used in severe respiratory infectious disease, especially among immunocompromised patients. This study aims to determine whether mNGS (using LRT specimen) guided antimicrobial treatment improves clinical prognosis of SCAP patients with immunocompromised conditions when compared with conventional antimicrobial treatment.
Lactoferrin is an iron-binding glycoprotein of the transferrin family which is expressed and refers to it as a "red protein from milk". It is known that lactoferrin can modulate the overall immune response in inflammatory disorders including modulation of cytokine/ chemokine production and immune regulation that resenting by interleukin (IL)-10. Children with failure to thrive have increase the risk of infectious disease. The mechanism behind this may be due to impaired of immune function, in which pro-inflammation response is increased (IL-1β, IL-6), while IL-10 acted as anti-inflammation response tends to reduces. High calorie formula (Oral Nutrition Supplement/ONS) are products used for oral nutrition support with the aim of increasing nutritional intake. they are a nutrition treatment option for when nutrition support has been identified beside dietary counselling. ONS are typically used in addition to a normal diet, when diet alone is insufficient to meet daily nutritional requirement due to infection or others. ONS should be treated like medication, ensure they are labelled with the patient's name and provided at the prescribed time. It is well established that nutritional deficiency or inadequate can impair immune function. Growing evidence suggest that for certain nutrients increased intake above currently recommended levels may help optimize immune function including improving the defense function and thus resistance to infection while maintaining tolerance. This study aims to analize the levels of IL-6 and IL- 10 in children with failure to thrive with infection before and after receiving the intervention of lactoferrin in high-calorie formula milk. This study is an observational study with a pre-, post-test design, with designed total subject is 80. The subject is healthy children with weight faltering aged 1-5 years diagnosed with infection (tuberculosis/TB or urinary tract infection/UTI)
Introduction: Oral candidiasis is an infectious disease caused by the growth of Candida colonies and their penetration into oral tissues when physical barriers and host defenses are weakened. It constitutes one of the most common pathologies within the field covered by Dentistry. Candida infections are found in at least 80% of AIDS patients and in a third of HIV infection cases. Systemic diseases such as diabetes and a wide pharmacological arsenal to which the general population is subjected, are other causes of the increase in the prevalence of this disease. In addition, the high prevalence of oral sequelae (hyposialia) in the population over 65 years of age, due to the specific characteristics of this age group, such as multiple pathologies and drug use, explains the presence of this disease in this segment. of the population One of the great difficulties for the study of this disease is the diversity of predisposing factors, which do nothing but throw greater confusion into the results of the different works. Objective: To evaluate the reduction/suppression of signs and symptoms of oral candidiasis in patients treated with head and neck RT, users of Vacucis or Placebo. Material and method: Patients will receive information regarding the trial and, if they meet the inclusion criteria and agree to participate in it, they will sign the informed consent. All patients will be informed following the usual care practice of the characteristics of their candidiasis infection as well as the possibilities and alternatives of treatment and their respective efficacy. A descriptive analysis of the sample in terms of prevalence will be carried out. Categorical variables will be described as frequency and percentage and continuous variables as mean and standard deviation or median and interquartile range depending on their adjustment to normality, which will be calculated with the Kolmogorov-Smirnov test. To study the effect of the vaccine on the evolution of candidiasis, the Chi-square test, Student's t test or the non-parametric Mann-Whitney test will be used. The association of prevalence with CFU in both groups will be analyzed using the ANOVA test. Those values of p < 0.05 will be considered significant.
This is a 5-year Hybrid Type 1 Effectiveness-Implementation Randomized Control Trial (RCT) that compares two models of linking and retaining individuals recently released from justice involvement to the continuum of community-based HIV prevention and treatment, HCV treatment, STI treatment, and opioid use disorder (OUD) prevention and treatment, medication for opioid use disorder (MOUD) service cascades of care.
This is a multi-center randomized controlled evaluator-masked trial designed to compare metagenomic deep sequencing (MDS) versus standard of care testing for improvement of outcomes for intraocular infections. Patients with presumed intraocular infections who meet the eligibility criteria will be randomized to receive MDS testing results or not to receive MDS testing results. All patients will receive standard-of-care testing to guide management. Enrolled patients will be followed at week 2, week 3-6 (randomization visit), and at 4 weeks after the randomization visit. The proportions of patients who received the appropriate therapy and the proportions of patients with improved outcome will be compared between arms. Patient quality of life, MDS performance, and the provider certainly of belief will be collected.
This is a single center pilot study involving a single study visit for participants, with remote follow up data collected at 24 hours. Follow up at 3 months and 6 months later occurs as standard of care. The purpose of the study is to find out if a new type of imaging tracer (68Ga-DFO) can be used to show infection in patients with vascular grafts using PET/CT scans. These infections may be associated with significant ill health and mortality and can be difficult to diagnose. Effective treatments can require major surgery and long-term antibiotic therapy which may not be well tolerated nor feasible. Development of new imaging tracers that could detect bacteria causing graft infections with PET-CT scanners has great potential to benefit patients being considered for vascular surgery. A PET-CT scan combines images from a CT (Computerised Tomography) scan and a PET (Positron Emission Tomography) scan. The CT scan takes a series of X-rays across the organs inside the body. The PET scan uses a mildly radioactive tracer to show up areas of activity inside the body. The 68Ga-DFO tracer mimics particles that bacteria make to take up iron from the body to help them grow. The investigators hope this new tracer will go to areas where bacteria are causing infection and tell if the graft is infected. The investigators hope this type of tracer could be a better way to show infection than the tests currently used to diagnose infection.
The global dissemination of carbapenem-resistant Enterobacteriaceae (CRE) and Pseudomonas aeruginosa (CRPA) are a significant threat to health care, especially for severely ill patients. Antibiotics currently used to treat CRE and CRPA infections are usually toxic and not very effective. Novel treatments include beta-lactamase inhibitors with broad-spectrum activity, among them IMI-REL. IMI-REL is a promising molecule due to the ability of REL to diminish carbapenem MICs to the susceptible range, potentially restoring the activity of this potent drug. However, few studies have systematically examined IMI-REL activity against a diverse clinical collection of CRE and CRPA strains, in particular from a region where the resistance is high, and the main mechanisms are in general unknown (Brazil- Latin America). As the use of molecular diagnostics becomes increasingly available in clinical settings, it is crucial to identify molecular markers predicting antimicrobial efficacy to guide therapeutic decision-making. In the present study, we will acess different species of CRE and CRPA from clinically relevant isolates to determine if the species, clonal lineage, and resistance gene profile, have influence to the response to IMI-REL.
Articular Implant Infection (AII) is itself a complicated diagnosis and a challenging condition to treat. In elderly patients, the application of existing recommendations is impeded by multiple frailties For a better knowledge of the long-term consequences of AII in elderly patient, the investigators conduct a prospective, multicentric study, whitch aim this is to better evaluate the burden of AII on elderly patients, in terms of quality of life. Secondly, the investigators would like to identify the factors that influence the prognosis, in order to guide further prospective research.
