Filter by:Progress in the diagnosis of infectious pathogens depends on the development of effective methods and the discovery of suitable biomarkers. There are several kinds of methods that have been used in diagnosis of various pathogens, such as microscopic examination, culture, serologic diagnosis or molecular approaches, etc. However, these methods have similar limitations, that is, the single detection of reagents. More importantly, physicians seldom consider infections with rare pathogens. Recently developed metagenomic next-generation sequencing (mNGS) has the capability to overcome limitations of traditional diagnostic tests. This new technology could identify all pathogens directly from sample with a single run in a hypothesis-free and culture-independent manner. Studies have shown that mNGS is more sensitive than traditional culture method in clinical conditions such as blood stream, respiratory and general infections. More importantly, due to unbiased sampling, mNGS is theoretically able to identify not only known but also unexpected pathogens or even discovery novel organisms. It should be noted that mNGS also has some limitations such as human genome contamination and possibly environmental microbial contamination. The vast majority of reads in mNGS are derived from human host. This would impede the overall analytical sensitivity of mNGS for pathogen detection. Host depletion methods or targeted sequencing may help to partially mitigate this disadvantage. As mNGS could not, by itself, define whether the detected microbe is the causative pathogen or environmental microorganism, a multidisciplinary discussion by clinicians, microbiologists as well as the lab technicians is required to interpret the result.

Phase 1 1. Develop an ED-ID biobank (named ePWAS-RID). Phase 2 2. Targeted research for the discovery of novel diagnostics, prognostics and therapeutics
Mycosis fungoides (MF) is an ultra-orphan disease of which the etiology remains unknown. MF is diagnosed by correlating clinical appearance with histopathological analysis of often multiple invasive skin punch biopsies. To move patient care and the development of novel treatments for MF forward, objective, sensitive and reliable tools that are preferably non-invasive are desired. Therefore, the objective of the current study is to phenotype the early stages of mycosis fungoides in detail and to assess the response of chlormethine (CL) gel monotherapy. With this approach the investigators aim to detect novel biomarkers and to establish methodologies for the (non-)invasive monitoring of MF.
The risk for invasive fungal infections is high in very low birth weight (VLBW) infants (< 1500 g) and highest for infants born at the youngest gestational ages who survive past the immediate postnatal period. Invasive fungal infections (IFIs) represent an increasing cause of severe morbidity and mortality in most neonatal intensive care units. Lactoferrin (LF) is secreted by epithelial cells into exocrine fluids: seminal fluid, tears, saliva, uterine secretions, and milk. LF is involved in innate immunity mechanisms with several documented anti-infective properties, including antifungal activity. Probiotics are microorganisms that are believed to provide health benefits when consumed. It is possible to adopt measures to modify the flora in our bodies and to replace the harmful microbes by useful microbes. There are certain commercially available strains of probiotic bacteria from the Bifido bacterium and Lactobacillus genera when taken by mouth in daily doses possess treatment efficacy
Self-care and self-medication are commonly the treatments of choice for the management of minor ailments. Minor ailments can be treated through community pharmacy using a Minor Ailment Service (MAS). The INDICA+PRO Impact Study, evaluated the clinical, economic and humanistic impact of a MAS, concluding that community pharmacies could greatly benefit the health system. Thus, the following objectives were defined for the INDICA+PRO implementation study. The primary objective is to implement a standardised MAS in usual practice in community pharmacy in Spain. The secondary objectives include an evaluation of the clinical and economic outcomes and the role and impact of two different models of change agents. A pragmatic study with an effectiveness-implementation hybrid design type 3 will be undertaken using the Framework for the Implementation of Services in Pharmacy (FISpH). The study will be carried between October 2020 and December 2022. Two type of practice change facilitators FaFa and SEFaFa. Their main function, using the Observe-Plan-Do-Study-Act process, will be to facilitate the implementation through individualised continuous support to providers of the MAS. The depth and breadth of support to pharmacist providers by each type of change agents will vary. Pharmaceutical Associations (PA) and/or Spanish Society of Community Pharmacy (SEFAC) will invite community pharmacies/pharmacists. Participating pharmacists will need to sign a commitment form. The second study population will consist of patients presenting with minor ailments or requesting a non-prescription medication. Recruitment of patients will be carried out by the pharmacist providers. The inclusion criteria will be: patients or caregivers (aged ≥18 years, or younger if they are accompanied by an adult) presenting with 31 minor ailments, grouped into five categories (respiratory, moderate pain, digestive, dermatological and other) with pre-agreed referral protocols. Other symptoms may be included at the discretion of the pharmacists. The exclusion criteria will be patients who do not provide informed consent. The patient/pharmacist intervention will consist of a MAS protocol adapted for each symptom. The consultation will be record in an electronic data capture system (SEFAC eXPERT®-) that provides a step-by-step approach with protocols and clinical information embedded. The FISpH model will be used to guide the implementation of MAS. Two types of change agents, FaFas and SeFaFas, previously trained for 18 hours, will be used to facilitate the implementation. During each of the stages (exploration, preparation, testing and operation, and initial sustainability), strategies will be used by FaFas and SeFaFas to moderate implementation factors. The impact of strategies will be evaluated. Data on pharmacy/pharmacist's provider performance and patient outcomes will be provided to pharmacist, change agents and PA and SEFAC. FaFas and SeFaFas will have a classification system for barriers and facilitators derived from the constructs in the Consolidated Framework for Implementation Research (CFIR). The classification system for implementation strategies consists of an adaptation of the facilitation activities listed by Dogherty et al. These will be documented in an electronic data capture system. FaFas will train their pharmacists (max. of 25 pharmacies) for 6 hours and subsequently provide at least monthly follow-up. The research team will provide ongoing feedback and support to the FaFas and SeFaFas through periodically, hold group meetings by video conference between the research group and all the FaFas and SeFaFas. The research group will provide formal reports on the implementation process and patient outcomes. Other forms of communication such as emails, telephone calls or WhatsApp messaging will also be available. Implementation and patient consultation process and outcome variables will be measured such as reach, fidelity and integration. Outcome service indicators will be clinical, economic and humanistic. A patient follow up will occur at a maximum of 10 days. Continuous variables will be reported using mean and standard deviation, or median and percentiles. Categorical variables will be reported using percentages. T Student's test or the ANOVA test or Kruskal-Wallis. χ2 test, Fisher's exact test or Yate's chi-squared will also be used. To determine the relationship between the dependent and the independent variables, logistic regression models will be performed including the variables with statistical significance in the bivariate model. The level of significance will be set at p <0.05. Machine learning and big data techniques are being considered for predictive modelling. The research team will only have access to de-identified data of pharmacists and patients. This study protocol has been approved by the Granada Research Ethics Committee on the 5th February 2020.
The purpose of the study is to investigate the role of the human immune response to candidemia/invasive candidiasis as it relates to the cytokine interferon-gamma.
Primary cutaneous T-cell lymphomas are a group of peripheral T-cell lymphomas that primarily involve the skin. Mycosis fungoides (MF) is the most frequent subtype. Most patients with early-stage MF (i.e., patches and plaques of the skin without extracutaneous involvement) have a good prognosis but a subset of patients progress to incurable advanced-stage disease with an overall survival (OS) less than 5 years and an impaired quality of life. We have recently identified the tumor clone frequency in lesional skin (measured by high-throughput sequencing of the TCRB locus) as the most important prognostic factor of progression-free survival (PFS) and OS in a retrospective analysis on 210 patients with early-stage MF (p<0.001). Phototherapy is a standard therapeutic option in early-stage MF but fails to eradicate the tumor clone from the skin. Low-dose total-skin electron-beam therapy (LDTSEBT, 12 Gy over a 3-week period) has been shown to be safe and highly effective in MF with an 88% overall response rate and a better safety profile compared to standard-dose total-skin electron-beam therapy, in a pooled analysis from 3 phase II trials on 33 patients and a retrospective analysis of 12 patients treated with LDTSEBT. We hypothesize that the use of LDTSEBT is associated with a significantly higher 1-year PFS compared to conventional treatment with phototherapy. Our secondary hypotheses are that LDTSEBT is associated with a higher tumor T-cell clone eradication compared to phototherapy, and improves OS and quality of life in patients with skin-limited MF. The main objective of this study is therefore to prospectively determine if LDTSEBT is associated with a higher 1-year progression-free survival in patients with early-stage mycosis fungoides, compared to conventional treatment with phototherapy. The primary endpoint is PFS at 12 months after study inclusion.
The goal of the current study is to evaluate the ability of CGB-400, a proprietary eutectic mixture of GRAS compounds, to clear the toenail fungal growth and improve the appearance of the fungus affected area(s). This is an open-label, single group POC study evaluating the effectiveness of CGB-400 Topical Gel for toenail fungal growth clearing. The study consists of a 12-week period with 5 clinic visits at the following timepoints: Baseline (Day 0), and Weeks 2, 6, and 12 and post-application follow-up at Week 24. The applications could be extended for an additional 12 weeks based on PI's observations. Approximately 15 subjects will be enrolled and subjected to application of CGB-400 Topical Gel. Subjects must be at least 18 years of age and will be selected by the concerned PI.
Opportunistic fungal infection is the most common opportunistic infection in AIDS patients, with the high mortality and recurrence rate due to the lack of standardized comprehensive diagnosis and treatment strategy. This project aims to combine traditional detection and observation indicators with molecular biology, serology and mass spectrometry identification technology to develop early screening and diagnostic strategies for opportunistic fungal infections in AIDS patients, explore scientific evaluation methods for anti-fungal efficacy and formulate comprehensive strategies for reducing the mortality and recurrence rate.
The aim of this study is to determine if fungal colonization is associated to severe bronchopulmonary dysplasia in premature infants less than 29 weeks of gestation, and to determine if an association exists between fungal colonization and complications of prematurity and death.
