An intranasal nanoparticle vaccine elicits protective immunity against Mycobacterium tuberculosis. Vaccine 2024:S0264-410X(24)00482-1. [PMID: 38704256 DOI: 10.1016/j.vaccine.2024.04.055] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/19/2023] [Revised: 04/15/2024] [Accepted: 04/18/2024] [Indexed: 05/06/2024]
Abstract
Mucosal vaccines have the potential to elicit protective immune responses at the point of entry of respiratory pathogens, thus preventing even the initial seed infection. Unlike licensed injectable vaccines, mucosal vaccines comprising protein subunits are only in development. One of the primary challenges associated with mucosal vaccines has been identifying and characterizing safe yet effective mucosal adjuvants that can effectively prime multi-factorial mucosal immunity. In this study, we tested NanoSTING, a liposomal formulation of the endogenous activator of the stimulator of interferon genes (STING) pathway, cyclic guanosine adenosine monophosphate (cGAMP), as a mucosal adjuvant. We formulated a vaccine based on the H1 antigen (fusion protein of Ag85b and ESAT-6) adjuvanted with NanoSTING. Intranasal immunization of NanoSTING-H1 elicited a strong T-cell response in the lung of vaccinated animals characterized by (a) CXCR3+ KLRG1- lung resident T cells that are known to be essential for controlling bacterial infection, (b) IFNγ-secreting CD4+ T cells which is necessary for intracellular bactericidal activity, and (c) IL17-secreting CD4+ T cells that can confer protective immunity against multiple clinically relevant strains of Mtb. Upon challenge with aerosolized Mycobacterium tuberculosis Erdman strain, intranasal NanoSTING-H1 provides protection comparable to subcutaneous administration of the live attenuated Mycobacterium bovis vaccine strain Bacille-Calmette-Guérin (BCG). Our results indicate that NanoSTING adjuvanted protein vaccines can elicit a multi-factorial immune response that protects from infection by M. tuberculosis.

Artificial intelligence for predictive biomarker discovery in immuno-oncology: a systematic review. Ann Oncol 2024; 35:29-65.

Abstract
BACKGROUND The widespread use of immune checkpoint inhibitors (ICIs) has revolutionised treatment of multiple cancer types. However, selecting patients who may benefit from ICI remains challenging. Artificial intelligence (AI) approaches allow exploitation of high-dimension oncological data in research and development of precision immuno-oncology. MATERIALS AND METHODS We conducted a systematic literature review of peer-reviewed original articles studying the ICI efficacy prediction in cancer patients across five data modalities: genomics (including genomics, transcriptomics, and epigenomics), radiomics, digital pathology (pathomics), and real-world and multimodality data. RESULTS A total of 90 studies were included in this systematic review, with 80% published in 2021-2022. Among them, 37 studies included genomic, 20 radiomic, 8 pathomic, 20 real-world, and 5 multimodal data. Standard machine learning (ML) methods were used in 72% of studies, deep learning (DL) methods in 22%, and both in 6%. The most frequently studied cancer type was non-small-cell lung cancer (36%), followed by melanoma (16%), while 25% included pan-cancer studies. No prospective study design incorporated AI-based methodologies from the outset; rather, all implemented AI as a post hoc analysis. Novel biomarkers for ICI in radiomics and pathomics were identified using AI approaches, and molecular biomarkers have expanded past genomics into transcriptomics and epigenomics. Finally, complex algorithms and new types of AI-based markers, such as meta-biomarkers, are emerging by integrating multimodal/multi-omics data. CONCLUSION AI-based methods have expanded the horizon for biomarker discovery, demonstrating the power of integrating multimodal data from existing datasets to discover new meta-biomarkers. While most of the included studies showed promise for AI-based prediction of benefit from immunotherapy, none provided high-level evidence for immediate practice change. A priori planned prospective trial designs are needed to cover all lifecycle steps of these software biomarkers, from development and validation to integration into clinical practice.

Abstract
Background Iron deficiency (ID) has been shown to be a significant co-morbidity in patients with heart failure (HF), independent of their anaemia status. Correction of ID has been shown to improve quality of life, recurrent heart failure hospitalizations and morbidity. A quality improvement project was designed to improve the assessment and treatment of iron deficiency in HF patients in our tertiary care centre. Methods and results An initial baseline dataset was collected, followed by two cycles of interventions to help improve the care of HF patients admitted to our hospital over a two-month period. The Plan-Do-Study-Act (PDSA) cycle approach was applied, with the first intervention involving raising awareness of the importance and need to assess the iron status of HF patients through education provided to doctors, nurses and patients. Furthermore, information leaflets were produced and disseminated across the medical wards and through social media forums. The post-intervention datasets were collected and compared to the baseline outcomes. Baseline data showed that only four (20%) of heart failure patients had their iron status checked. Following the interventions, screening for ID increased to 80% (16), of which 85% (11) of those who identified as iron deficient received intravenous iron replacement. Conclusion The project was successful in improving the practice of screening for iron deficiency and intravenous replacement of iron in patients with HF.

Case report: a giant cell-rich gnathic bone lesion in a child with pycnodysostosis. FRONTIERS IN ORAL HEALTH 2023; 4:1188443. [PMID: 37288425 PMCID: PMC10242096 DOI: 10.3389/froh.2023.1188443] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/17/2023] [Accepted: 04/24/2023] [Indexed: 06/09/2023] Open
Abstract
Pycnodysostosis is a skeletal dysplasia characterized by short stature, generalized osteosclerosis, acro-osteolysis, and recognizable facial features. Oral manifestations are commonly described and include a high-arched palate with dental crowding and malocclusion, hypoplastic enamel, and retained deciduous teeth with impacted permanent teeth, and there is an increased risk of developing osteomyelitis of the jaw. We report here the history of a 9-year-old male with the typical facial and skeletal phenotype of pycnodysostosis but novel oral features. He presented with bilateral progressive facial swelling, which caused functional impairment with chewing and contributed to his severe obstructive sleep apnea (OSA). The severity of his OSA required surgical intervention, and the lesions were resected. Extensive bone remodeling and replacement by fibrous tissue were noted on submucosal dissection, and bilateral subtotal maxillectomies were required. The histopathology of the biopsied lesion was consistent with a giant cell-rich lesion. Genetic testing identified a pathogenic homozygous variant in the CTSK gene, c.953G > A, p. (Cys318Tyr). The proband had a good postsurgical response with sustained improvement in his sleep OSA. We present here the history and clinical characteristics of a patient with typical features of pycnodysostosis and an unusual presentation and histopathology of gnathic bone lesions. This report adds to the body of literature on this rare condition and also highlights the finding of giant cell-rich lesions of the gnathic bones. Giant cell-rich lesions in pycnodysostosis have previously been reported in two cases in the literature. While there is not enough evidence to support a certain association with pycnodysostosis, it is prudent to consider regular oral dental reviews in affected individuals to identify pathology early and avoid such life-threatening complications.

Abstract
Funding Acknowledgements Type of funding sources: None. Introduction Decompensation of heart failure leading (HF) to hospitalisation is the single most important drain on healthcare resources when managing patients with left ventricular systolic dysfunction. Cardiac resynchronisation therapy with/without defibrillators (CRT-P/D) decreases hospitalisation due to HF and improves survival while implantable cardiac defibrillators (ICD"s) have a favourable effect on the former. Proprietary software algorithms embedded in these complex devices give an early warning to clinicians when decompensation of HF is imminent allowing preventative action to be undertaken. HeartLogic (HL) is one such new algorithm in Boston Scientific CRT-D/ICD devices using multiple sensors to track 5 physiological parameters, combining them into one composite Index, with an Alert being triggered if the Index is >16. The COVID-19 pandemic, due to multiple reasons, resulted in a significant decrease in availability of routine HF services in the United Kingdom, especially during the initial lockdown period from 23rd March to 1st July 2020. Aim To assess the impact of the COVID-19 pandemic, using HL, in patients with HF and complex devices. Materials and Methods Retrospective analysis of patients in a tertiary care cardiac centre in whom the HL software had been activated in March/April 2019 (n = 49) and comparison of those with (Group A n = 21) and without (Group B n = 28) an Alert (HLA) during the COVID-19 pandemic. Results (Table): Whole cohort n = 49. Age: 72 ± 12 years, Median: 75, Range: 36-95. 36/49 (73.5%) males. Type of device implanted: Resonate X4 CRT-D: 28/49 (57.1%); Momentum CRT-D: 8/49 (16.3%); Resonate ICD: 13/49 (26.5%). Ischaemic aetiology of HF: 35/49 (71.4%), Total duration of HL monitoring: 632 ± 7 days (median: 632; range: 626-672). There was no difference in the age, gender, and type of device implanted between Group A and Group B. Over nearly ∼1 year of monitoring in each of the groups, Group A had more unstable HF with 10/21 (47.6%) having their first HLA during the pandemic. Multiple HLA"s, longer period in HLA and those with ischaemic aetiology of HF were higher in Group A. 17/40 (42.5%) HLA"s in Group A were within the first lockdown period (March - July). 24/28 (85.7%) patients in Group B had no HLA"s either before or during the pandemic. There was no difference in the HLA score between Groups A and B. Conclusion In this limited group of patients with a medium term follow-up, using the HeartLogic software, patients with ischaemic aetiology of HF and those with more HLA"s prior to the pandemic did worse than those who no HLA"s. First HLA"s, multiple alerts and longer duration of alerts in this group of patients suggests a lack of access to adequate HF services during the pandemic. It has implications with regard to how HF services are configured in future whenever resources are constrained.

Abstract
This article reports on two experiments that investigated 59 children's ability to estimate distances from a map. In Experiment 1, totally blind children, children with residual vision, and sighted children were given a map showing the position of three objects on a path, two of which were present on the actual path. The children were asked to use the map to work out the position of the third object. The visually impaired children performed less well than did the sighted children, and an analysis of the children's strategies indicated that the majority of visually impaired children did not know an effective way to work out distances from the map. In Experiment 2, the visually impaired children were given a brief training in how to calculate distances from a map and then they were retested. After training, the children's performance improved.

Abstract
This article reports on three experiments in which totally blind children and children with residual vision were asked to estimate directions between landmarks in a large-scale layout of objects. The children experienced the layout either directly, by walking around it, or indirectly by examining a tactile map. The authors found that the use of tactile maps considerably facilitated the performance of the totally blind children. The theoretical and practical implications of these findings are discussed.

Abstract
INTRODUCTION Diabetic foot ulcers (DFUs) are devastating, common, and costly. The mortality of veterans following a DFU is sobering with ulceration recognized as a significant marker of disease severity. Given the dramatic impact of diabetic foot complications to the veteran and the US health care system, the US Department of Veterans Affairs (VA) has long recognized the importance of preventive care for those at risk. Telemedicine has been suggested as a modality to reach veterans at high risk of chronic wound formation. OBSERVATIONS The purpose of this review is to: (1) present the evidence supporting once-daily remote temperature monitoring (RTM), a telemedicine approach critical to improving both veteran access to care and diabetic foot outcomes; (2) summarize a 2017 study published by VA providers who have advanced clinical understanding of RTM; (3) present previously unpublished data from this study comparing high-risk VA and non-VA cohorts, highlighting the opportunity for additional focus on DFU prevention within the VA; and (4) report on recent VA use of a RTM technology based on this research, emphasizing lessons learned and best practices. CONCLUSIONS There is a significant opportunity to shift diabetic foot care from treatment to prevention, improving veteran outcomes and reducing resource utilization. RTM is an evidence-based, recommended, but underused telemedicine solution that can catalyze this needed paradigm shift.

Abstract
This chapter's goal is to interrogate the intersectional significance of race and socioeconomic status for children of varied statuses of human vulnerability. It provides a context-connected, culture acknowledging, systems model and identity formation perspective. This strategy is ideal for delineating behavioral consistencies (and interpreting inconsistencies). When operationalized with programming opportunities, it accommodates the nation's diversity and aids the interpretation of findings. This chapter is divided into several sections: First, it interrogates critical insights afforded by a "resiliency-vulnerability" approach; second, it draws attention to the roles of culture, culturally competent practices, and justice-informed contexts for children's perception-based "meaning making" as each-increasingly with age-navigates multiple social ecologies. Third, it shifts to and emphasizes the intersectionally relevant factors of race (e.g., identifiability and skin color stereotyping) and socioeconomic status (i.e., both low resourced and privileging situations); and following a synthesis of the previous sections-as Section 4-it then frames the cumulative and integrated conceptual strategy (phenomenological variant of ecological systems theory: PVEST). In Section 5, the chapter presents theory-focused exemplars to illustrate the theory's efficacy, which are followed by results of two recent preliminary application projects. Salient is that the two projects presenting preliminary findings add to and afford important child development insights salient as strategies for neutralizing intersectionality effects and maximizing resiliency outcomes. To sum, synthesizing several decades of scholarship, theorizing, contemporary research and programming application efforts, the handbook chapter concludes with suggested strategies for creating more informed policies and practices relevant to all children's overall resiliency, healthy development and well-being.

Abstract
Abstract
Francisella tularensisis the causative agent of the human disease tularemia. F. tularensisinfects a variety of cells, including macrophages, in order to cause pathogenicity. As few as 10 inhaled microorganisms cause a lethal infection by over-activating the host’s own inflammatory response. Differences in the intensity of the inflammatory response exist between the sexes which leads to differences in sensitivity to autoimmune and infectious disease. Males tend to be more susceptible to infectious diseases whereas females tend to be more susceptible to autoimmune diseases. However, our preliminary data unexpectedly demonstrated that female mice were more susceptible to F. tularensis-mediated disease than male mice. We hypothesize that the elevated inflammatory state of females may make them more susceptible to F. tularensis disease and that the M1 and M2 macrophage subsets may determine this differential inflammatory response. Naïve M1 and M2 macrophages will be purified from male and female mice and infected in vitro to directly compare cellular responses between male and female mice. In parallel, M0 macrophages will be differentiated in vitro prior to infection for similar comparison.

Abstract
OBJECTIVE Juvenile dermatomyositis (JDM) is the most common form of idiopathic inflammatory myopathy in children. While outcomes are generally thought to be good, persistence of skin rash is a common problem. The goal of this study was to describe the development of clinical treatment plans (CTP) for children with JDM characterized by persistent skin rash despite complete resolution of muscle involvement. METHODS The Childhood Arthritis and Rheumatology Research Alliance, a North American consortium of pediatric rheumatologists and other healthcare providers, used a combination of Delphi surveys and nominal group consensus meetings to develop CTP that reflected consensus on typical treatments for patients with JDM with persistent skin rash. RESULTS Consensus was reached on patient characteristics and outcome assessment. Patients should have previously received corticosteroids and methotrexate (MTX). Three consensus treatment plans were developed. Plan A added intravenous immunoglobulin (IVIG) if it was not already being used. Plan B added mycophenolate mofetil, while Plan C added cyclosporine. Continuation of previous treatments, including corticosteroids, MTX, and IVIG, was permitted in plans B and C. CONCLUSION Three consensus CTP were developed for use in children with JDM and persistent skin rash despite complete resolution of muscle disease. These CTP reflect typical treatment approaches and are not to be considered treatment recommendations or standard of care. Using prospective data collection and statistical methods to account for nonrandom treatment assignment, it is expected that these CTP will be used to allow treatment comparisons, and ultimately determine the best treatment for these patients.

BACKGROUND Parents struggle when making treatment decisions for children with arthritis or other chronic conditions. Understanding their decision-making process is an essential step towards improving the decision-making experience. The objective of this study was to describe parents' information needs and the influences on their decision making about treatment with TNF-α inhibitors. METHODS Survey domains were developed based on qualitative data and cognitive interviewing. We mailed the survey to parents of children with juvenile idiopathic arthritis or inflammatory bowel disease who had initiated treatment with TNF-α inhibitors in the prior 2 years. Data were analyzed using descriptive and non-parametric statistics. RESULTS Survey response rate was 54.9 %. Each item had <2 % missing responses. Parents used an array of information sources when deciding about treatment with TNF-α inhibitors. Resources other than their child's specialist were most often used to increase confidence in parents' decisions or because they wanted to know more about other people's experiences being treated with TNF-α inhibitors, rather than due to a lack of understanding. All but two (cost and route of administration) of the influential decision factors were very or extremely important to the majority of participants with factors related to long-term side effects, treatment efficacy, and disease impact being most important. CONCLUSIONS This study describes parents' information needs and influential factors in treatment decision making. Results suggest that future work should be aimed at helping families weigh risks and benefits, such as through decision support interventions, as well as developing opportunities to include people beyond the family and physician in the decision-making process.

Abstract
Abstract
γ9δ2 T cells provide a natural bridge between innate and adaptive immunity and are prominently induced by both tuberculosis (TB) infection and bacillus Calmette Guérin (BCG) vaccination. Mycobacteria-expanded γ9δ2 T cells represent only a subset of the simple phosphoantigen (IPP and HMBPP)-responsive γ9δ2 T cells, this subset expresses a more oligoclonal set of TCR sequences, and only this subset efficiently recognizes and inhibits intracellular BCG/Mtb. We have been searching for new mycobacterial antigens capable of inducing the unique subset of γ9δ2 T cells that can recognize mycobacteria-infected macrophages and mediate protective effects inhibiting intracellular mycobacterial growth. We first ruled out protein, nucleic acid and apolar lipids with basic separations and enzymatic digestions. Acid hydrolysis, which digests complex carbohydrate structures, had the largest effect on eliminating Mtb fraction specific activity. Organic extractions resulted in sub-fractions with >100 fold enriched specific activity. A combination of MS, NMR, TLC indicate that methyl-glucose lipopolysaccharides (mGLP) are predominant components of the most active fractions. We are currently attempting to use synthetic techniques to confirm the specific activity of mGLP for induction of protective γ9δ2 T cells. These results have important implications for the development of new immunotherapeutic approaches for prevention/treatment of TB.

The heightened inflammatory response makes females are more susceptible to F. tularensis-mediated death (INM1P.444). THE JOURNAL OF IMMUNOLOGY 2015.

Abstract
Abstract
The zoonotic infectious disease, Francisella tularensis, the causative agent for human tularemia, elicits high cytokine levels as a result of rampant inflammation, a condition referred to as “cytokine storm.” This cytokine storm is responsible for the severity of symptoms and ultimately for the death of the host. Though men have a tendency to be exposed to the pathogen more frequently than women, do to its presence in wild animals, women have a significantly greater inflammatory response than do men. Therefore, we asked whether their enhanced inflammatory response might make women more susceptible to tularemia-mediated death. Male and female mice were infected with F. tularensis and their survival and inflammatory response monitored. Subsequently, the role of sex hormones was considered by infecting gonadectomized mice. On average, 15% female mice survived infection compared with 90% of male mice. In addition, the female mice displayed an increased serum cytokine storm compared with male mice despite similar levels of bacterial growth. We seek to identify the factors controlling this increased susceptibility of female mice. This line of investigation may lead to the development of novel therapeutics and/or treatment strategies specific to women exposed to F. tularensis.

Experimental validation of a novel compact focusing scheme for future energy-frontier linear lepton colliders. PHYSICAL REVIEW LETTERS 2014; 112:034802.

Abstract
A novel scheme for the focusing of high-energy leptons in future linear colliders was proposed in 2001 [P. Raimondi and A. Seryi, Phys. Rev. Lett. 86, 3779 (2001)]. This scheme has many advantageous properties over previously studied focusing schemes, including being significantly shorter for a given energy and having a significantly better energy bandwidth. Experimental results from the ATF2 accelerator at KEK are presented that validate the operating principle of such a scheme by demonstrating the demagnification of a 1.3 GeV electron beam down to below 65 nm in height using an energy-scaled version of the compact focusing optics designed for the ILC collider.

ROCK1 & 2 perform overlapping and unique roles in angiogenesis and angiosarcoma tumor progression. Curr Mol Med 2013; 13:205-19.

Abstract
The serine/threonine protein kinase paralogs ROCK1 & 2 have been implicated as essential modulators of angiogenesis; however their paralog-specific roles in endothelial function are unknown. shRNA knockdown of ROCK1 or 2 in endothelial cells resulted in a significant disruption of in vitro capillary network formation, cell polarization, and cell migration compared to cells harboring non-targeting control shRNA plasmids. Knockdowns led to alterations in cytoskeletal dynamics due to ROCK1 & 2-mediated reductions in actin isoform expression, and ROCK2-specific reduction in myosin phosphatase and cofilin phosphorylation. Knockdowns enhanced cell survival and led to ROCK1 & 2-mediated reduction in caspase 6 and 9 cleavage, and a ROCK2-specific reduction in caspase 3 cleavage. Microarray analysis of ROCK knockdown lines revealed overlapping and unique control of global transcription by the paralogs, and a reduction in the transcriptional regulation of just under 50% of VEGF responsive genes. Finally, paralog knockdown in xenograft angiosarcoma tumors resulted in a significant reduction in tumor formation. Our data reveals that ROCK1 & 2 exhibit overlapping and unique roles in normal and dysfunctional endothelial cells, that alterations in cytoskeletal dynamics are capable of overriding mitogen activated transcription, and that therapeutic targeting of ROCK signaling may have profound impacts for targeting angiogenesis.

Abstract
Routine daily bathing of intensive care (ICU) patients with topical chlorhexidine reduces meticillin-resistant Staphylococcus aureus (MRSA) acquisition. The aim of this study was to investigate whether repeated five-day cycles of daily topical octenidine could result in a similar effect. This was a two-year retrospective, uncontrolled study in a mixed medical and surgical ICU/high dependency unit, demonstrating a 76% reduction in MRSA acquisition but no significant reduction in all ICU-acquired bacteraemias. Chlorhexidine use is increasing but resistance is being reported. This pilot study found a similar reduction in MRSA acquisition with octenidine as an alternative to chlorhexidine. Further study is required to establish causality.
