The UK’s Joint Committee on Vaccination and Immunisation has recommended maximising the number of people vaccinated with first doses at the expense of early booster vaccinations, based on single dose efficacy against symptomatic COVID-19 disease.1-3At the time of writing, three COVID-19 vaccines have been granted emergency use authorisation in the UK, including the BNT162b2 mRNA COVID-19 vaccine (Pfizer-BioNTech). A vital outstanding question is whether this vaccine prevents or promotes asymptomatic SARS-CoV-2 infection, rather than symptomatic COVID-19 disease, because sub-clinical infection following vaccination could continue to drive transmission. This is especially important because many UK HCWs have received this vaccine, and nosocomial COVID-19 infection has been a persistent problem.Through the implementation of a 24 h-turnaround PCR-based comprehensive HCW screening programme at Cambridge University Hospitals NHS Foundation Trust (CUHNFT), we previously demonstrated the frequent presence of pauci- and asymptomatic infection amongst HCWs during the UK’s first wave of the COVID-19 pandemic.4 Here, we evaluate the effect of first-dose BNT162b2 vaccination on test positivity rates and cycle threshold (Ct) values in the asymptomatic arm of our programme, which now offers weekly screening to all staff.Vaccination of HCWs at CUHNFT began on 8th December 2020, with mass vaccination from 8th January 2021. Here, we analyse data from the two weeks spanning 18thto 31st January 2021, during which: (a) the prevalence of COVID-19 amongst HCWs remained approximately constant; and (b) we screened comparable numbers of vaccinated and unvaccinated HCWs. Over this period, 4,408 (week 1) and 4,411 (week 2) PCR tests were performed from individuals reporting well to work. We stratified HCWs <12 days or > 12 days post-vaccination because this was the point at which protection against symptomatic infection began to appear in phase III clinical trial.226/3,252 (0·80%) tests from unvaccinated HCWs were positive (Ct<36), compared to 13/3,535 (0·37%) from HCWs <12 days post-vaccination and 4/1,989 (0·20%) tests from HCWs ≥12 days post-vaccination (p=0·023 and p=0·004, respectively; Fisher’s exact test, Figure). This suggests a four-fold decrease in the risk of asymptomatic SARS-CoV-2 infection amongst HCWs ≥12 days post-vaccination, compared to unvaccinated HCWs, with an intermediate effect amongst HCWs <12 days post-vaccination.A marked reduction in infections was also seen when analyses were repeated with: (a) inclusion of HCWs testing positive through both the symptomatic and asymptomatic arms of the programme (56/3,282 (1·71%) unvaccinated vs 8/1,997 (0·40%) ≥12 days post-vaccination, 4·3-fold reduction, p=0·00001); (b) inclusion of PCR tests which were positive at the limit of detection (Ct>36, 42/3,268 (1·29%) vs 15/2,000 (0·75%), 1·7-fold reduction, p=0·075); and (c) extension of the period of analysis to include six weeks from December 28th to February 7th 2021 (113/14,083 (0·80%) vs 5/4,872 (0·10%), 7·8-fold reduction, p=1x10-9). In addition, the median Ct value of positive tests showed a non-significant trend towards increase between unvaccinated HCWs and HCWs > 12 days post-vaccination (23·3 to 30·3, Figure), suggesting that samples from vaccinated individuals had lower viral loads.We therefore provide real-world evidence for a high level of protection against asymptomatic SARS-CoV-2 infection after a single dose of BNT162b2 vaccine, at a time of predominant transmission of the UK COVID-19 variant of concern 202012/01 (lineage B.1.1.7), and amongst a population with a relatively low frequency of prior infection (7.2% antibody positive).5This work was funded by a Wellcome Senior Clinical Research Fellowship to MPW (108070/Z/15/Z), a Wellcome Principal Research Fellowship to PJL (210688/Z/18/Z), and an MRC Clinician Scientist Fellowship (MR/P008801/1) and NHSBT workpackage (WPA15-02) to NJM.

Tam Hunt [1], Jonathan SchoolerUniversity of California Santa Barbara Synchronization, harmonization, vibrations, or simply resonance in its most general sense seems to have an integral relationship with consciousness itself. One of the possible “neural correlates of consciousness” in mammalian brains is a combination of gamma, beta and theta synchrony. More broadly, we see similar kinds of resonance patterns in living and non-living structures of many types. What clues can resonance provide about the nature of consciousness more generally? This paper provides an overview of resonating structures in the fields of neuroscience, biology and physics and attempts to coalesce these data into a solution to what we see as the “easy part” of the Hard Problem, which is generally known as the “combination problem” or the “binding problem.” The combination problem asks: how do micro-conscious entities combine into a higher-level macro-consciousness? The proposed solution in the context of mammalian consciousness suggests that a shared resonance is what allows different parts of the brain to achieve a phase transition in the speed and bandwidth of information flows between the constituent parts. This phase transition allows for richer varieties of consciousness to arise, with the character and content of that consciousness in each moment determined by the particular set of constituent neurons. We also offer more general insights into the ontology of consciousness and suggest that consciousness manifests as a relatively smooth continuum of increasing richness in all physical processes, distinguishing our view from emergentist materialism. We refer to this approach as a (general) resonance theory of consciousness and offer some responses to Chalmers’ questions about the different kinds of “combination problem.”  At the heart of the universe is a steady, insistent beat: the sound of cycles in sync…. [T]hese feats of synchrony occur spontaneously, almost as if nature has an eerie yearning for order. Steven Strogatz, Sync: How Order Emerges From Chaos in the Universe, Nature and Daily Life (2003) If you want to find the secrets of the universe, think in terms of energy, frequency and vibration.Nikola Tesla (1942) I.               Introduction Is there an “easy part” and a “hard part” to the Hard Problem of consciousness? In this paper, we suggest that there is. The harder part is arriving at a philosophical position with respect to the relationship of matter and mind. This paper is about the “easy part” of the Hard Problem but we address the “hard part” briefly in this introduction.  We have both arrived, after much deliberation, at the position of panpsychism or panexperientialism (all matter has at least some associated mind/experience and vice versa). This is the view that all things and processes have both mental and physical aspects. Matter and mind are two sides of the same coin.  Panpsychism is one of many possible approaches that addresses the “hard part” of the Hard Problem. We adopt this position for all the reasons various authors have listed (Chalmers 1996, Griffin 1997, Hunt 2011, Goff 2017). This first step is particularly powerful if we adopt the Whiteheadian version of panpsychism (Whitehead 1929).  Reaching a position on this fundamental question of how mind relates to matter must be based on a “weight of plausibility” approach, rather than on definitive evidence, because establishing definitive evidence with respect to the presence of mind/experience is difficult. We must generally rely on examining various “behavioral correlates of consciousness” in judging whether entities other than ourselves are conscious – even with respect to other humans—since the only consciousness we can know with certainty is our own. Positing that matter and mind are two sides of the same coin explains the problem of consciousness insofar as it avoids the problems of emergence because under this approach consciousness doesn’t emerge. Consciousness is, rather, always present, at some level, even in the simplest of processes, but it “complexifies” as matter complexifies, and vice versa. Consciousness starts very simple and becomes more complex and rich under the right conditions, which in our proposed framework rely on resonance mechanisms. Matter and mind are two sides of the coin. Neither is primary; they are coequal.  We acknowledge the challenges of adopting this perspective, but encourage readers to consider the many compelling reasons to consider it that are reviewed elsewhere (Chalmers 1996, Griffin 1998, Hunt 2011, Goff 2017, Schooler, Schooler, & Hunt, 2011; Schooler, 2015).  Taking a position on the overarching ontology is the first step in addressing the Hard Problem. But this leads to the related questions: at what level of organization does consciousness reside in any particular process? Is a rock conscious? A chair? An ant? A bacterium? Or are only the smaller constituents, such as atoms or molecules, of these entities conscious? And if there is some degree of consciousness even in atoms and molecules, as panpsychism suggests (albeit of a very rudimentary nature, an important point to remember), how do these micro-conscious entities combine into the higher-level and obvious consciousness we witness in entities like humans and other mammals?  This set of questions is known as the “combination problem,” another now-classic problem in the philosophy of mind, and is what we describe here as the “easy part” of the Hard Problem. Our characterization of this part of the problem as “easy”[2] is, of course, more than a little tongue in cheek. The authors have discussed frequently with each other what part of the Hard Problem should be labeled the easier part and which the harder part. Regardless of the labels we choose, however, this paper focuses on our suggested solution to the combination problem.  Various solutions to the combination problem have been proposed but none have gained widespread acceptance. This paper further elaborates a proposed solution to the combination problem that we first described in Hunt 2011 and Schooler, Hunt, and Schooler 2011. The proposed solution rests on the idea of resonance, a shared vibratory frequency, which can also be called synchrony or field coherence. We will generally use resonance and “sync,” short for synchrony, interchangeably in this paper. We describe the approach as a general resonance theory of consciousness or just “general resonance theory” (GRT). GRT is a field theory of consciousness wherein the various specific fields associated with matter and energy are the seat of conscious awareness.  A summary of our approach appears in Appendix 1.  All things in our universe are constantly in motion, in process. Even objects that appear to be stationary are in fact vibrating, oscillating, resonating, at specific frequencies. So all things are actually processes. Resonance is a specific type of motion, characterized by synchronized oscillation between two states.  An interesting phenomenon occurs when different vibrating processes come into proximity: they will often start vibrating together at the same frequency. They “sync up,” sometimes in ways that can seem mysterious, and allow for richer and faster information and energy flows (Figure 1 offers a schematic). Examining this phenomenon leads to potentially deep insights about the nature of consciousness in both the human/mammalian context but also at a deeper ontological level.

The construct of wellbeing has been criticised as a neoliberal construction of western individualism that ignores wider systemic issues including increasing burden of chronic disease, widening inequality, concerns over environmental degradation and anthropogenic climate change. While these criticisms overlook recent developments, there remains a need for biopsychosocial models that extend theoretical grounding beyond individual wellbeing, incorporating overlapping contextual issues relating to community and environment. Our first GENIAL model \cite{Kemp_2017} provided a more expansive view of pathways to longevity in the context of individual health and wellbeing, emphasising bidirectional links to positive social ties and the impact of sociocultural factors. In this paper, we build on these ideas and propose GENIAL 2.0, focusing on intersecting individual-community-environmental contributions to health and wellbeing, and laying an evidence-based, theoretical framework on which future research and innovative therapeutic innovations could be based. We suggest that our transdisciplinary model of wellbeing - focusing on individual, community and environmental contributions to personal wellbeing - will help to move the research field forward. In reconceptualising wellbeing, GENIAL 2.0 bridges the gap between psychological science and population health health systems, and presents opportunities for enhancing the health and wellbeing of people living with chronic conditions. Implications for future generations including the very survival of our species are discussed.

IntroductionConsistent with World Health Organization (WHO) advice [1], UK Infection Protection Control guidance recommends that healthcare workers (HCWs) caring for patients with coronavirus disease 2019 (COVID-19) should use fluid resistant surgical masks type IIR (FRSMs) as respiratory protective equipment (RPE), unless aerosol generating procedures (AGPs) are being undertaken or are likely, when a filtering face piece 3 (FFP3) respirator should be used [2]. In a recent update, an FFP3 respirator is recommended if “an unacceptable risk of transmission remains following rigorous application of the hierarchy of control” [3]. Conversely, guidance from the Centers for Disease Control and Prevention (CDC) recommends that HCWs caring for patients with COVID-19 should use an N95 or higher level respirator [4]. WHO guidance suggests that a respirator, such as FFP3, may be used for HCWs in the absence of AGPs if availability or cost is not an issue [1].A recent systematic review undertaken for PHE concluded that: “patients with SARS-CoV-2 infection who are breathing, talking or coughing generate both respiratory droplets and aerosols, but FRSM (and where required, eye protection) are considered to provide adequate staff protection” [5]. Nevertheless, FFP3 respirators are more effective in preventing aerosol transmission than FRSMs, and observational data suggests that they may improve protection for HCWs [6]. It has therefore been suggested that respirators should be considered as a means of affording the best available protection [7], and some organisations have decided to provide FFP3 (or equivalent) respirators to HCWs caring for COVID-19 patients, despite a lack of mandate from local or national guidelines [8].Data from the HCW testing programme at Cambridge University Hospitals NHS Foundation Trust (CUHNFT) during the first wave of the UK severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic indicated a higher incidence of infection amongst HCWs caring for patients with COVID-19, compared with those who did not [9]. Subsequent studies have confirmed this observation [10, 11]. This disparity persisted at CUHNFT in December 2020, despite control measures consistent with PHE guidance and audits indicating good compliance. The CUHNFT infection control committee therefore implemented a change of RPE for staff on “red” (COVID-19) wards from FRSMs to FFP3 respirators. In this study, we analyse the incidence of SARS-CoV-2 infection in HCWs before and after this transition.

E3 ligases constitute an important component of proteostasis machinery which plays a critical role in the survival of malaria parasite through post-translational modifications of its protein-substrates. In contrast to humans, parasite E3 ligases have not been extensively studied. Here, we characterize a unique Plasmodium E3 ligase that has both RING and HECT-like features with zinc-coordinating domains. Plasmodium encodes a single RING-between-RING (RBR) E3 ligase that has evolutionarily diverged from human and other intracellular parasites. This RBR-E3 ligase is expressed throughout the erythrocytic phase of P. falciparum lifecycle. Immunoprecipitation experiments showed that Pf RBR-E3 ligase catalyzes K6, K11, K48 and K63 mediated polyubiquitination hinting towards its diverse biological roles (DNA repair, proteasomal degradation, mitochondrial quality control). We observed that Pf RBR-E3 ligase interacts with UBCH5 and UBC13 family of E2-conjugating enzymes. Through mutational analysis, we identified residues in RING1 and RING2 domains that are critical for ubiquitination activity and protein stability of Pf RBR-E3 ligase. Our experiments showed that Pf RBR-E3 ligase participates in maintenance of organellar homeostasis and exhibits differences in immunofluorescence profile upon exposure of parasite to different genotoxic (MMS) and proteotoxic (MG132, FCCP and artemisinin derivative) stress. Our study opens up avenues for exploring the client substrates of Pf RBR-E3 ligase and using this knowledge to design substrate-specific protein degradation based alternative intervention strategies for malaria.

Background: Hemophagocytic lymphohistiocytosis (HLH) is a life-threatening disease. Relapsed/refractory disease is the main cause of death. This study is aimed to determine the prognostic indicators for relapsed/refractory disease in childhood HLH (R/R HLH). Procedure: Infants and children under 18 years of age who were diagnosed with HLH according to HLH-2004 criteria, MAS-HLH criteria for rheumatologic diseases, or H-score undergoing treatment in Chiang Mai University hospital between 2010 – 2022 were included. Demographic data, clinical characteristics, and laboratory parameters were retrospectively reviewed. Results: Out of 86 childhood HLH cases, 30 patients (34.9%) experienced R/R HLH. All patients with primary HLH developed R/R HLH. The most common form of secondary HLH was infection-associated hemophagocytic syndrome (IAHS), comprising 43 cases. Of these, 37.2% had relapsed or refractory disease. Univariable analysis identified several potential risk factors for R/R HLH, including younger age, severe disease status, higher HLH-2004 criteria scores, higher H-scores, overt DIC, higher pSOFA scores, and increased levels of aspartate aminotransferase, total bilirubin, and direct bilirubin. Multivariable logistic regression analysis revealed that a pSOFA score of ≥ 8 and age < 3 years were independent risk factors for R/R HLH, with adjusted odds ratios of 6.35 (95% confidence interval [CI], 1.18 – 34.19; p = 0.032) and 3.62 (95% CI, 1.04 – 12.63; p = 0.044), respectively. Conclusions: Children with HLH who have a pSOFA score of ≥ 8, or are younger than 3 years, are at a higher risk of relapsed or refractory disease. Further evaluation of management strategies in this context is warranted.

Introduction:Myocardial infarction with nonobstructive coronary artery disease (MINOCA) is a group of conditions that share common characteristics and is characterized by the absence of ≥50% stenosis of coronary arteries and without any evidence of atherosclerotic plaque rupture [1]. A study conducted by Waller et al. reported that 4% to 7% of all patients diagnosed with AMI, do not have underlying atherosclerotic coronary disease on autopsy or angiography [2].Coronary artery embolism is a rare and important non-atherosclerotic cause of acute myocardial infarction (AMI), and the first case of AMI secondary to coronary embolism was reported in 1856 by Rudolf Virchow and was classified initially as a precipitating factor for type-II MI, now recognized as one of the cause of MINOCA [3]. Coronary embolism (CE) is more frequently reported in infective endocarditis patients and it mainly involves the left main coronary artery system due to flow characteristics and aortic morphology [4, 5]. CE may also originate from mural thrombus within the left-sided cardiac chambers, but it has rarely been reported in the literature [6]. Most cases of coronary embolism in the literature have been reported secondary to infective endocarditis, valvular heart diseases, and atrial fibrillation [7-9]. Here, we are reporting a case of a 74-year-old female, who had a chronic history of atrial fibrillation on anticoagulation with questionable compliance and was admitted with sepsis and takotasubo cardiomyopathy and later developed AMI secondary to coronary embolism to the left anterior descending artery.

Introduction: Despite a reported understanding of basic radiation physics principles, students face barriers that hinder effective translation of this knowledge into clinical practice, potentially leading to suboptimal outcomes.The objectives of this cross-sectional descriptive research are to assess the level of radiation physics knowledge among clinical radiography students, evaluate their ability to apply this knowledge in clinical settings, identify barriers hindering successful application, and provide recommendations for improved integration. Material and method: The study was conducted among clinical students (4 th year and 5 th year) of the department of radiography and radiological sciences, University of Nigeria, Enugu campus, Enugu state. The study design was a cross-sectional descriptive study which enables to collect data at a specific point in time. The study population comprised of students who are currently in 4 th and 5 th year in the department of medical radiography and radiological sciences. The population has a total number of 500 students. All clinical radiography students who are willing to participate in this research were included in this research Results: Among 220 participants from the University of Nigeria’s Department of Radiography and Radiological Sciences, 81.4% expressed thorough teaching of radiation physics during pre-clinical training, while 68.3% reported an excellent understanding. However, 64.3% cited disinterest due to perceived complexity, 42.0% noted a gap between theoretical teaching and practical application, and 84.6% mentioned a lack of fear of radiation’s biological effects. Suggestions for improvement included a dedicated curriculum (90.0%), increased teaching duration (69.7%), expert involvement (95.10%), hands-on training (95.5%), interactive learning methods (93.2%), and collaborative training approaches (95.0%). Conclusion: This research underscores the importance of refining radiation physics education to bridge theory and practice effectively.

Purpose: We aim to identify risk factors associated with pathological upgrading/downgrading after conization in patients with cervical high-grade squamous intraepithelial lesion and provide risk stratification management based on machine learning predictive model. Methods: 1. This retrospective study included patients who visited Obstetrics and Gynecology Hospital of Fudan University from January 1 to December 31, 2019, and were diagnosed with cervical high-grade squamous intraepithelial lesion (HSIL) by colposcopy directed biopsy (CDB) and subsequently underwent conization. A wide variety of data were collected from medical records, including demographic data, laboratory findings, colposcopy descriptions, and pathological results. Patients were categorized into three groups according to their post-conization pathological results: LSIL or below (downgrading group), HSIL (HSIL group), and cervical cancer (upgrading group). 2. Univariate and multivariate analysis were conducted to obtain the independent risk factors for pathological changes in cervical HSIL patients. 3. Machine learning prediction models were established and evaluated, subsequently verified in external testing data. Results: 1. A total of 1585 patients were included, with 65 cases (4.1%) being upgraded to cervical cancer after conization, 1147 cases (72.4%) remaining HSIL, and 373 cases (23.5%) being downgraded to LSIL or below. 2. Multivariate analysis results showed that a 2% decrease in the incidence of pathologic downgrade was found for each additional year of age and each 1% increase in lesion area. Patients with cytology >LSIL (OR=0.33, 95%CI: 0.21-0.52), HPV infection (OR=0.33, 95%CI: 0.14-0.81), HPV 33 infection (OR=0.37, 95%CI: 0.18-0.78), coarse punctate vessels on colposcopy examination (OR=0.14, 95%CI: 0.06-0.32), HSIL lesions in endocervical canal(OR=0.48, 95%CI: 0.30-0.76) , and HSIL impression (OR=0.02, 95%CI: 0.01-0.03) were less likely to experience pathologic downgrading after conization. 3. The independent risk factors of pathological upgrading to cervical cancer after conization including: age (OR=1.08, 95%CI: 1.04-1.12), HPV16 infection (OR=4.07, 95%CI: 1.70-9.78), the presence of coarse punctate vessels during colposcopy examination (OR=2.21, 95%CI: 1.08-4.50), atypical vessels (OR=6.87, 95%CI: 2.81-16.83), and HSIL lesions in endocervical canal (OR=2.91, 95%CI: 1.46-5.77). 4. In 6 machine learning prediction models, the BP neural network model demonstrated highest and most uniform predictive performance in the downgrading group, HSIL group, and upgrading group, with AUCs of 0.90, 0.84, and 0.69, respectively, sensitivities of 0.74, 0.84 and 0.42, specificities of 0.90, 0.71 and 0.95, accuracies of 0.74, 0.84 and 0.95. In the external testing set, the BP neural network model showed a higher predictive performance than the logistic regression model, with the overall AUC of 0.91. Thus, a web-based prediction tool (http://115.29.79.17:8082/) was developed. Conclusion:BP neural network prediction model has excellent predictive performance and can be used for risk stratification of CDB diagnosed HSIL patients.

Over the past decade, our research group has found that plant responses to combined abiotic stresses are unique and cannot be inferred from studying plants exposed to individual stresses. Adaptive mechanisms involve changes in gene expression, ion regulation, hormonal balance, and metabolite biosynthesis or degradation. Understanding how these mechanisms integrate from stress perception to biochemical and physiological adjustments is a major challenge in abiotic stress signaling studies. Today, vast amounts of -omics data (genomics, transcriptomics, proteomics, metabolomics, phenomics) are readily available. Additonally, each –omic level is regulated and influenced by the others, highlighting the complexity of plant metabolism’s response to stress. Considering abscisic acid (ABA) as a key regulator in plant abiotic stress responses, in our study, ABA-deficient plants (flc) underwent single or combined salinity and heat stresses were evaluated and different -omics analyses were conducted. Significant changes in biomass, photosynthesis, ions, transcripts, and metabolites occurred in mutant plants under single or combined stresses. Exogenous ABA application in flc mutants did not fully recover plant phenotypes or metabolic levels but induced cellular reprogramming with changes in specific markers. Multi-omic analysis aimed to identify ABA-dependent, ABA-independent, or stress-dependent markers in plant responses to single or combined stresses. We demonstrated that studying different -omics together identifies specific markers for each stress condition not detectable individually. Our findings provide insight into specific metabolic markers in plant responses to single and combined stresses, highlighting specific regulation of metabolic pathways, ion absorption, and physiological responses crucial for plant tolerance to climate change.

Introduction: Scrub typhus is a neglected life threatening acute febrile illness caused by bacteria Orientia tsutsugamushi and it is a vector-borne zoonotic disease. In 2009, scrub typhus outbreak at Gedu has awakened Bhutan on the awareness and testing of the disease.Information and data of the study highlights the need for in depth surveillance, awareness among prescribers and initiate preventive measures in the country. Methods: We used retrospective descriptive study through review of laboratory registers across three health centres in Zhemgang district, south central Bhutan. The laboratories registers have been transcribed into CSV file using Microsoft excel. Variables of interest were collected from the registers and then analysed using open statistical software R, (R Core Team (2020). R: A language and environment for statistical computing. R Foundation for Statistical Computing, Vienna, Austria.) And use of mStats package, (MyoMinnOo (2020). mStats: Epidemiological DataAnalysis. R package version 3.4.0.) Results: Of the total 922 tests prescribed for suspected scrub typhus in the three health centers in Zhemgang, only 8.2 % (n=76) were tested positive. Of these, Panbang Hospital had highest reported positive for scrub typhus with 56.6 %( n=43) followed by Yebilaptsa Hospital 35.5 %( n=27) and Zhemgang Hospital with 7.9 %( n=6). The female gender is comparably more affected as opposed to male with 57.9% (n=44) of the positive cases being female. The prevalence of scrub typhus seems to be affected by the seasonal variation as the months of Spring, Summer and Autumn together accounts for 98.7%(n=75) of total positive cases. The year 2019 noted significant scrub typhus cases accounting to 89.5 %(n=68) of the total positive cases over the two years. Conclusions:The overall tests tested positive of the scrub typhus infection within two years was 8.2%.
