Background: Indoleamine 2, 3-dioxygenase (IDO) is an immunoregulatory enzyme that metabolises tryptophan to immunosuppressive kynurenines. We investigated whether IDO activity is associated with the size of HIV reservoirs. Methods: In this cross-sectional study, total HIV DNA in PBMCs from 127 HIV-infected patients receiving antiretroviral therapy (ART) was quantified. Tryptophan and kynurenine concentrations, as well as microbial translocation markers were measured in plasma samples...

Viral fitness quantifies the degree of virus adaptation to a given environment. How viral fitness can influence the mutant spectrum complexity of a viral quasispecies subjected to lethal mutagenesis has not been investigated. Here we document that two high fitness hepatitis C virus populations display higher resistance to the mutagenic nucleoside analogues favipiravir and ribavirin than their parental, low fitness HCV. All populations, however, exhibited a mutation transition bias indicative of active mutagenesis...

Purpose Pancreatic ductal adenocarcinoma (PDAC) has a poor prognosis, with a 5-year survival of < 10% because of diffuse symptoms leading to late-stage diagnosis. That survival could increase significantly if localized tumors could be detected early. Therefore, we used multiparametric analysis of blood samples to obtain a novel biomarker signature of early-stage PDAC. The signature was derived from a large patient cohort, including patients with well-defined early-stage (I and II) PDAC. This biomarker signature was validated subsequently in an independent patient cohort...

Research has demonstrated the effectiveness of family-based programs for reducing adolescent risk behaviors and promoting adolescent health; however, parent engagement, specifically in terms of recruitment and retention, remains a consistent challenge. Recruitment rates for family-based prevention programs range from 3 to 35%, while, on average, 28% of caregivers drop out before program completion. Thus, engagement of parents in prevention programming is of utmost concern to ensure families and youth benefit from implementation of family-based programs...

BACKGROUND: Recently, a newly developed cancer-specific multiattribute utility instrument based on the widely used health-related quality of life instrument, the European Organisation for Research and Treatment of Cancer QLQ-C30, was introduced: the QLU-C10D. For the elicitation of utility weights, a discrete choice experiment (DCE) was designed. Our aim was to investigate the DCE in terms of individual choice consistency and utility estimate consistency by applying a test-retest design...

Handover is widely identified by the National Confidential Enquiry into Patient Outcome and Death, the Royal College of Physicians (RCP) and Health Foundation as an area that can lead to shortcomings in patient care. We recognised that the current weekend handover process in the Trauma and Orthopaedics department at Frimley Park Hospital was dated, time-consuming and did not promote handover of sufficient patient details. The Royal College of Surgeons, British Medical Association and RCP have guidelines on handover...

A key step in nutrient sensing is activation of the master growth regulator, mTORC1 kinase, on the lysosomal membrane. Nutrients enable mTORC1 scaffolding by a complex composed of the Rag GTPases (Rags) and Ragulator, but the underlying mechanism of mTORC1 capture is poorly understood. Combining dynamic imaging in cells and reconstituted systems, we uncover an affinity switch that controls mTORC1 lifetime and activation at the lysosome. Nutrients destabilize the Rag-Ragulator interface, causing cycling of the Rags between lysosome-bound Ragulator and the cytoplasm, and rendering mTORC1 capture contingent on simultaneous engagement of two Rag-binding interfaces...

Introduction: Many electronic health records fail to support information uptake because they impose low-level information organization tasks on users. Clinical concept-oriented views have shown information processing improvements, but the specifics of this organization for critical care are unclear. Objective: To determine high-level cognitive processes and patient information organization schema in critical care. Methods: We conducted an open card sort of 29 patient data elements and a modified Delphi card sort of 65 patient data elements...

In studies of human episodic memory, the phenomenon of reactivation has traditionally been observed in regions of occipitotemporal cortex (OTC) involved in visual perception. However, reactivation also occurs in lateral parietal cortex (LPC), and recent evidence suggests that stimulus-specific reactivation may be stronger in LPC than in OTC. These observations raise important questions about the nature of memory representations in LPC and their relationship to representations in OTC. Here, we report two fMRI experiments that quantified stimulus feature information (color and object category) within LPC and OTC, separately during perception and memory retrieval, in male and female human subjects...

BACKGROUND: In haematology and oncology, in particular in the setting of allogeneic hematopoietic stem cell transplantation (allo-HSCT), VRE colonization rates are high due to previous hospital stays and preceding antibiotic treatment and colonized patients have a lower overall survival (OS). OBJECTIVE: We reanalysed our previously published cohort, to unravel which colonization timepoints before and during allo-HSCT might be predictive for the subsequent outcome...

BACKGROUND: There has been considerable interest in providing antenatal dietary and lifestyle advice for women with obesity or who are overweight during pregnancy, as a strategy to limit gestational weight gain and improve maternal and infant health. However, such antenatal interventions appear to have a modest effect on gestational weight gain and other clinical pregnancy and birth outcomes and additional strategies are required.Metformin is an oral insulin-sensitising medication that acts to decrease blood glucose concentrations...

Allogeneic hematopoietic stem cell transplantation (allo-HSCT) offers potential cure to acute myeloid leukemia (AML) patients. However, infections with commensal bacteria are an important cause for non-relapse mortality (NRM). We have previously described the impact of multidrug-resistant organism (MDRO) colonization on the survival of allo-HSCT patients. In the aforementioned publication, according to consensus, we there did not consider the opportunistic gram-negative bacterium Stenotrophomonas maltophilia (S...

Automated design of enzymes with wild-type-like catalytic properties has been a long-standing but elusive goal. Here, we present a general, automated method for enzyme design through combinatorial backbone assembly. Starting from a set of homologous yet structurally diverse enzyme structures, the method assembles new backbone combinations and uses Rosetta to optimize the amino acid sequence, while conserving key catalytic residues. We apply this method to two unrelated enzyme families with TIM-barrel folds, glycoside hydrolase 10 (GH10) xylanases and phosphotriesterase-like lactonases (PLLs), designing 43 and 34 proteins, respectively...

BACKGROUND: Rheumatic heart disease is a high-burden condition in Australian Aboriginal communities. We evaluated a stepped-wedge, community, randomized trial at 10 Aboriginal communities from 2013 to 2015. A multifaceted intervention was implemented using quality improvement and chronic care model approaches to improve delivery of penicillin prophylaxis for rheumatic heart disease. The trial did not improve penicillin adherence. This mixed-methods evaluation, designed a priori , aimed to determine the association between methodological approaches and outcomes...

To study the contribution of T-cell receptors (TCR) to resulting T cell responses, we studied three different human αβ TCRs, reactive to the same gp100-derived peptide presented in the context of HLA-A*0201. When expressed in primary CD8 T cells, all receptors elicited classic antigen-induced IFN-γ responses, which correlated with TCR affinity for peptide-MHC in the order T4H2>R6C12>SILv44. However, SILv44 elicited superior IL-17A release. Importantly, in vivo, SILv44-transgenic T cells mediated superior anti-tumor responses to 888-A2+ human melanoma tumor cells upon adoptive transfer into tumor-challenged mice while maintaining IL-17 expression...
