Objectives/Goals: Aims are to identify the gaps and discrepancies between cancer care teams at Princess Margaret (PM) and primary care providers (PCPs). To ensure the transition from hospital care at PM into the community integrates the expressed needs of PCPs and cancer specialists. To ensure PCPs have the necessary resources to provide high-quality care to patients. Methods/Study Population: Phase 1 is the preparation phase, which consists of searching the literature and conducting contextual inquiry with experts in relevant fields, such as cancer survivorship and primary care. This phase is crucial to the planning of this project as the information gathered will be used to define the problem space and outline the scope of the project. Next (phases 2 and 3) we aim to create and distribute surveys to PCPs to gather data on current protocols and resources. We plan to distribute this survey by emailing PCPs and accessing PCP networks. Upon completion of the survey, we will review the data and assess which areas need further investigation. Then, we will create an interview guide keeping in mind the areas that need to be supplemented and aiming to validate the need. Results/Anticipated Results: A resource that presents guidelines for PCPs to assist in them taking on follow-up care responsibilities for low-risk cancer survivorship patients. These guidelines may include information such as communication pathways between PCPs and the PM Cancer Care team, expected follow-up care measures, and timeframes for follow-up care. The development of this guideline will assist in alleviating the burden on the PM Cancer Centre system as it will facilitate low-risk patients transitioning back to family care. Discussion/Significance of Impact: There is an increasing demand for oncology services post-cancer treatment at the PM Cancer Centre and the current cancer model follow-up care is not sustainable by oncologists alone. There is a need to explore innovative personalized pathways to follow-up care based on an individual’s needs and integrate family doctors.
This Element delves into the relationship between logic and the sciences, a topic brought to prominence by Quine, who regarded logic as methodologically and epistemologically akin to the sciences. For this reason, Quine is seen as the forefather of anti-exceptionalism about logic (AEL), a stance that has become prevalent in the philosophy of logic today. Despite its popularity and the volume of research it inspires, some core issues still lack clarity. For one thing, most works in the debate remain vague on what should count as logic and what should count as a science. Furthermore, the terms of the comparison are rarely specified and discussed in a systematic way. This Element purports to advance the debate on these crucial issues with the hope of fostering our understanding of the fundamentals of AEL. This title is also available as Open Access on Cambridge Core.
Colorectal cancer (CRC) represents a relevant public health problem, with high incidence and mortality in Western countries. CRC can occur as sporadic (65%–75%), common familial (25%), or as a consequence of an inherited predisposition (up to 10%). While unravelling its genetic basis has been a long trip leading to relevant clinical implementation over more than 30 years, other contributing factors remain to be clarified. Among these, micro-organisms have emerged as critical players in the development and progression of the disease, as well as for CRC treatment response. Fusobacterium nucleatum (Fn) has been associated with CRC development in both pre-clinical models and clinical settings. Fusobacteria are core members of the human oral microbiome, while being less prevalent in the healthy gut, prompting questions about their localization in CRC and its precursor lesions. This review aims to critically discuss the evidence connecting Fn with CRC pathogenesis, its molecular subtypes and clinical outcomes.
Borderline personality disorder (BPD) is a severe mental disorder characterized by emotional dysregulation, impulsive behaviors, and difficulties in interpersonal relationships. Despite the poor understanding of the underlying biological processes, the oxytocin (OXT) system may be involved in and mediate some of BPD’s symptomatic and behavioral aspects. To clarify OXT’s role in BPD, we assessed its plasma levels and modulations induced by psychotherapies in patients.
Methods
Fifty BPD patients and 28 healthy controls (HC) participated in the study; patients were randomly assigned to two psychotherapeutic treatments: metacognitive interpersonal therapy and structured clinical management. Clinical and psychometric measures were assessed, and plasma was collected at baseline (T0) and in patients after 6 (T6) and 12 (T12) months of treatment. OXT was quantified by a radioimmunoassay technique.
Results
BPD patients showed lower plasma OXT at T0 than HC (p = 0.002), and a correlation was observed (r = −0.36, p = 0.017) between low OXT concentrations and high Attachment Style Questionnaire – Italian Version–Preoccupation with Relationships subscale scores. OXT changed significantly over time in patients (p = 0.049) with an increase particularly evident from baseline to T6 (p = 0.022), without significant difference between treatment groups. OXT changes (T0 − T12) inversely correlated with symptom improvement as changes in the Zanarini Rating Scale for borderline personality disorder (r = 0.387, p = 0.006) and the Difficulties in Emotion Regulation Scale (r = 0.387, p = 0.005) scores during treatment.
Conclusions
OXT alteration in BPD patients and the regularizing effect of long-term psychotherapies support an involvement of the OXT system in the disease and in treatment impact. More research is needed to fully understand the underlying causal mechanisms linking OXT with pathogenesis and psychotherapy outcomes.
We present an agent-based model to study how the network structure of a scientific community could impact the public uptake of science, and how this impact is influenced by scientific uncertainty and affinity bias. For unbiased agents, a highly connected scientific network decreases the probability that the public favors the correct theory. For biased agents, however, a moderately connected scientific network causes the public to favor the correct theory more often. This results from the competition between the scarcity of information (for poorly connected agents) and the spread of misleading information (for highly connected agents). Adding more scientists strengthens both effects.
Since the 1780s, Western philosophy has been largely under the spell of Immanuel Kant's transcendental philosophy. In this book, Maurizio Ferraris offers a number of important criticisms of Kant in a book of two parts, written twenty-one years apart. The first part of the book, 'Observation', originally published in 2001, lays the foundations of Ferraris' New Realism, foreshadowing the realist turn that has become characteristic of 21st century philosophy. The second part, 'Speculation', written in 2021, outlines a complete metaphysical theory of realism. What ties both parts of the book together is the notion of hysteresis, the ability of effects to survive even when their causes have ceased to exist.
Laboratory experiments have been often replaced by online experiments in the last decade. This trend has been reinforced when academic and research work based on physical interaction had to be suspended due to restrictions imposed to limit the spread of Covid-19. Therefore, data quality and results from web experiments have become an issue which is currently investigated. Are there significant differences between lab experiments and online findings? We contribute to this debate via an experiment aimed at comparing results from a novel online protocol with traditional laboratory settings, using the same pool of participants. We find that participants in our experiment behave in a similar way across settings and that there are at best weakly significant and quantitatively small differences in behavior observed using our online protocol and physical laboratory setting.
This Element examines performance in postmillennial China through the lens of postsocialism. The fragmented ontology of Chinese postsocialism captures the structural contradictions of a political system that supports a neoliberal economy while continuing to promote socialist values. This study explores how the ideological ambivalence and cultural paradoxes that characterise the postsocialist condition are embodied and represented in performance. Focusing on independent practitioners and postdramatic practices, it builds on theorisations of postsocialism as a state of temporal disjunction to propose a tripartite taxonomy structured around past, present, and future temporal regimes. The categories of postsocialist hauntologies, postsocialist realisms, and postsocialist futurities are introduced to investigate performance works that respectively revisit the socialist past, document present realities, and envision future imaginations. The intersection of competing temporalities and their performative manifestations reflects the disjunctive constitution of contemporary China, where past socialist legacies and futurological ambitions coexist within a fractured postsocialist present.
Large language models (LLMs) have significantly advanced artificial intelligence (AI) and natural language processing (NLP) by excelling in tasks like text generation, machine translation, question answering and sentiment analysis, often rivaling human performance. This paper reviews LLMs’ foundations, advancements and applications, beginning with the transformative transformer architecture, which improved on earlier models like recurrent neural networks and convolutional neural networks through self-attention mechanisms that capture long-range dependencies and contextual relationships. Key innovations such as masked language modeling and causal language modeling underpin leading models like Bidirectional encoder representations from transformers (BERT) and the Generative Pre-trained Transformer (GPT) series. The paper highlights scaling laws, model size increases and advanced training techniques that have driven LLMs’ growth. It also explores methodologies to enhance their precision and adaptability, including parameter-efficient fine-tuning and prompt engineering. Challenges like high computational demands, biases and hallucinations are addressed, with solutions such as retrieval-augmented generation to improve factual accuracy. By discussing LLMs’ strengths, limitations and transformative potential, this paper provides researchers, practitioners and students with a comprehensive understanding. It underscores the importance of ongoing research to improve efficiency, manage ethical concerns and shape the future of AI and language technologies.
The Prime Diet Quality Score (PDQS) is a rapid dietary screener that assesses diet quality. It has been associated with cardiovascular disease (CVD) in a US population(1) and validated in a UK/Irish population against 4-day food dairies(2). Food Frequency Questionnaires (FFQ) are the most commonly used dietary assessment instrument in large epidemiological studies(3). To reduce the burden of standard dietary assessment methodology, having a valid screener such as the PDQS that can be applied to FFQ data may be especially relevant to public health(4,5). This study aimed to explore how the PDQS applied to EPIC FFQ data compares to the PDQS collected directly to assess diet quality in a population at risk of CVD on the Island of Ireland.
The PAD-Q trial is a six-month, parallel, randomised, controlled, single-blinded intervention study conducted at Queen’s University Belfast and University College Dublin. Volunteers at risk of CVD by being overweight and either having hypertension, hypercholesterolaemia and/or smoking, and who had a low PDQS score (≤21) were recruited. PDQS provides a total score ranging 0-42 derived from the sum of intake level scores of 21 healthy and unhealthy food groups. To apply the PDQS to the FFQ data, the FFQ food items were matched to the most appropriate PDQS food group or left uncoded when no appropriate match could be made. Intakes from FFQ were calculated into an estimation of weekly portions to enable calculation of scores according to PDQS categories. Pearson correlation coefficients, ICCs and weighted kappa were used to analyse correlation and agreement between total PDQS scores, and Spearman correlation coefficients for individual PDQS food items. Comparison of scores from individual PDQS groups were analysed via Wilcoxon test, with p-values <0.05 considered statistically significant.
In total, n = 152 participants completed baseline questionnaires. Mean age of participants was 49 years (SD: 12), 70% were female, 29.5% were classified with overweight and 70.5% with obesity. PDQS total score derived from FFQ data (15.0 (SD: 3.7)) was correlated (r = 0.69, p<0.01) with PDQS total score at baseline (15.5 (SD: 4.2)). Similar association was observed via ICC (0.68 (95%CI: 0.58−0.76)). Weighted kappa indicated moderate agreement between measures (0.52 (SE: 05)). In the analysis of individual food group scores, correlation (r) ranged 0.32 - 0.68 (p<0.01). PDQS applied to FFQ demonstrated higher scores for most (9/13) of the healthy PDQS food groups and lower scores for all the unhealthy PDQS food groups (7/7) compared to PDQS data.
Diet quality assessed via PDQS applied to FFQ data was significantly moderately correlated with diet quality assessed via PDQS at baseline in the PAD-Q trial. Results are comparable with dietary questionnaire validation studies. FFQ data higher estimated the intake of both healthy and unhealthy PDQS food groups compared to PDQS data.
Central nervous system (CNS)-active polypharmacy is frequent and potentially harmful in older patients. Data on its burden outside the USA and European countries remain limited.
Aims
To estimate the period prevalence of and factors associated with out-of-hospital CNS-active polypharmacy in older adults.
Method
We used data from a cohort of out-patients aged ≥60 years affiliated to the Hospital Italiano de Buenos Aires’ health maintenance organisation on 1 January 2021. A CNS-active polypharmacy event was defined as the concurrent exposure to ≥3 CNS-active medications (i.e. antidepressants, anti-epileptics, antipsychotics, benzodiazepines, Z-drugs and opioids) through filled out-of-hospital prescriptions. We calculated the period prevalence of CNS-active polypharmacy for 2021. We identified factors associated with CNS-active polypharmacy using a multivariable logistic regression model to estimate odds ratios and 95% confidence intervals (CI).
Results
We included 63 857 patients. Pre-existing mental health diagnoses included anxiety (21%), depressive (14%) and sleep (11%) disorders. CNS-active polypharmacy occurred in 4535 patients, for a period prevalence of 7.1% (95% CI: 6.9–7.3%). The combination of an antidepressant, an antipsychotic and a benzodiazepine accounted for 21% of the CNS-active polypharmacy events. Frontotemporal dementia (odds ratio: 14.67; 95% CI: 4.47–48.20), schizophrenia (odds ratio: 7.93; 95% CI: 4.64–13.56), bipolar disorder (odds ratio: 7.20; 95% CI: 5.45–9.50) and depressive disorder (odds ratio: 3.50; 95% CI: 3.26–3.75) were associated with CNS-active polypharmacy.
Conclusions
One in 14 adults aged 60 years and older presented out-of-hospital CNS-active polypharmacy. Future studies should evaluate measures to reduce CNS-active medication use in this population.
Declining labor force participation of older men throughout the 20th century and recent increases in participation have generated substantial interest in understanding the effect of public pensions on retirement. The National Bureau of Economic Research's International Social Security (ISS) Project, a long-term collaboration among researchers in a dozen developed countries, has explored this and related questions. The project employs a harmonized approach to conduct within-country analyses that are combined for meaningful cross-country comparisons. The key lesson is that the choices of policy makers affect the incentive to work at older ages and these incentives have important effects on retirement behavior.
The field of psychosomatics has experienced many waves of “celebrity” since its origin. Its historical origin is impossible to precisely locate in time, one may argue that medicine since its very beginning has been psychosomatic in nature. In very recent times, many clinicians and researchers even from different backgrounds than psychosomatic medicine or psychiatry have expressed disappointment and worry about the excessive fragmentation of medical sciences, providing evidence in support and advocating towards the so-called holistic approach and integrated care. The old lesson of psychosomatic medicine, then, appears more contemporary than ever. This is also because it has been able to stay coherent but at the same time integrate the enormous progresses in the understanding of physiology and pathophysiology that medical sciences have witnessed in the last decades.
The presentation will focus on the most striking scientific production of 2023 in the field of psychosomatics, to show the contributions in its three souls of research, training and clinical activities and to outline the stimulating though sometimes difficult dialogue between this area of behavioural sciences and the rest of psychiatry.
There is an increasing need for valid, rapid diet screening tools. A significant association between the Prime Diet Quality Score (PDQS) and reduced risk of cardiovascular disease (CVD) has been demonstrated in the US but evidence of its use in Europe is lacking. The aim of this study was to amend the PDQS for a UK/Irish population and determine validity and reliability in those at risk of CVD. Participants were recruited via online adverts across the island of Ireland. The PDQS was amended for a UK/Irish population and participants completed PDQS and reference measure (4-day food diary (FD)) on two occasions. PDQS score was calculated directly from PDQS and indirectly from FDs. Validity was determined using Spearman correlation coefficients (SCCs) (r), intraclass correlation coefficients (ICCs) and weighted kappa. Reliability was determined using SCCs (r), ICCs, weighted kappa and coefficient of variation.
‘Data were available for n = 115 (Month 0) and n = 108 (Month 3) participants for validity and n = 110 for reliability assessment (PDQS completed at both timepoints)’. PDQS score from PDQS was significantly correlated with PDQS score from FDs at months 0 (r = 0.59, P < 0.01) and 3 (r = 0.65, P < 0.01), with similar associations observed via ICCs. Weighted kappa indicated moderate agreement. PDQS score at month 0 was significantly correlated with PDQS score at month 3 (r = 0.78, P < 0.01), with similar associations observed via ICCs. Weighted kappa indicated moderate agreement. Results indicate that the amended PDQS is a valid and reliable tool to determine diet quality in a UK/Irish population at risk of CVD.
Background: Pineal region tumors are a heterogenous group of pathologies often symptomatic due to occlusive hydrocephalus leading to elevated intracranial pressure (ICP). High ICP may not always be associated with clinical signs. A non-invasive technique for assessment of ICP is measuring the optic nerve sheath diameter (ONSD). The goal of this study was to determine the utility of preoperative and postoperative ONSD measurements for assessment of elevated ICP in children with pineal region tumors. Methods: Retrospective data analysis was performed in patients operated for pineal region tumors at our tertiary care center between 2003 and 2022. Preoperative and postoperative MRI scans were reviewed. Clinical data and ONSD at multiple time points were analyzed and correlated. Results: Thirty-four patients with forty operative cases met the inclusion criteria. Hydrocephalus was seen in 80% of patients preoperatively (n=32/40). Presence of hydrocephalus was associated with significantly elevated ONSD preoperatively (p=0.006) and postoperatively (p=0.017). There was significant decrease in ONSD immediately postoperatively (p<0.001), at 3 months (p<0.001) and 12 months (p<0.001). In patients without hydrocephalus, no significant changes in ONSD were observed (p=0.369). Conclusions: ONSD is a useful adjunct for the identification of high ICP preoperatively and evaluation of treatment response postoperatively in patients presenting with pineal region tumors.
Sour foods, such as citrus fruits, some berries and fermented foods provide a range of nutrients and benefits important to mental health [1]. When sourness is perceived as unpleasant, intake of these foods may be reduced affecting mental health. Early research has shown changes to sour taste perception in depression and stress however, changes in anxiety have not been studied [4-8]. To address this gap and build on the knowledge base, a survey was conducted in which participants (n = 424) rated recalled intensity and liking of sour index foods and completed the Depression, Anxiety, and Stress Scale (DASS-21) to measure these states. Variations in sour taste and mood have been demonstrated between females and males, hence the data were explored for sex-differences. Standard least squares regression (post hoc Tukey’s HSD) compared means between groups, and nominal logistic regression assessed differences in distributions between categories. Recalled sour intensity was 16-19.2% higher in those with scores indicative of mild depression than in those with normal scores in the total sample (p range 0.03-0.04), and 17.9-21.3% higher in females (p values were 0.03). There were no differences in sour taste intensity between the intergroup means for anxiety or stress and no associations between sour liking and any of the mood states. The results suggest that the sourness of index foods increases in depression. Further research to elucidate the biological processes and possible taste-related genetic influences that may be occurring would be beneficial. With this knowledge it may be possible to screen for mood conditions by measuring changes to sour taste that appear alongside other signs and symptoms, create more tailored dietary interventions and develop additional therapeutics.
4-H, which is the largest youth organization in the country, has evolved over time. Historically, there has been a disconnect between university-based researchers and practitioners who implement 4-H programs in the field. In part because of this mismatch and because there has been a focus on subject matter content, 4-H as an organization has struggled with articulating the theory of change that underlies its programming. Recent developments in understanding the science of learning and development and recent efforts to translate positive youth development research into practice are promising. Based at land-grant universities, 4-H is well positioned to capitalize on these developments and intentionally apply them in practice. This chapter highlights 4-H programming examples to illustrate developmental principles and concludes with next steps to address challenges and increase alignment with developmental science.
Here we describe a new species of the genus Saccocoelioides found parasitizing Astyanax dissimilis Garavello & Sampaio, Psalidodon bifasciatus (Garavello and Sampaio) and Bryconamericus ikaa Casciotta, Almirón & Azpelicueta from the Iguazu National Park, Misiones province, Argentina. Saccocoelioides miguelmontesi n. sp. was studied based on morphological and molecular (28S rDNA and COI mtDNA sequences) data. The COI mtDNA tree indicated that the specimens collected from the three fish hosts are conspecific, with an intragroup p-distance of 0%. The new species shows an intermediate morphological configuration between the diminutive and robust forms described for Saccocoelioides by Curran (2018). Although, in the 28S rDNA tree, it is placed in a well-supported clade with the two robust species analysed (S. elongatus and S. magnus; p-distance of 1 and 2%, respectively), it differs from the robust group by the range of body size, mature egg size, oral and ventral sucker size, sucker ratio, oral sucker to pharynx ratio, and post-cecal or post-testis/body length percentage. Our results led us to redefine the robust group as having eggs shorter or equal in length to the pharynx. Saccocoelioides miguelmontesi n. sp. the 10th species reported from Argentina and the 7th species within the robust group.
The second manifestation of hysteresis is iteration, to be understood as a property not of being, but of becoming. Consider, by way of example, a natural process such as the transmission of the genetic code; an artifactual process such as the splintering of a flint; and a cultural process such as the formation of a language or ritual. In each of these cases we are dealing with a succession of repeated acts (the copying of the code, the repeated percussion of the flint, the iteration of certain gestures or certain sounds). Little by little, each of these iterations gives rise to a being, both in the form of praxis, i.e. of action (for example, a ritual dance or a conversational exchange), and in that of poiesis, i.e. of production (the genesis of a life form, an arrowhead, a literary work or a legal code). The characteristic of acts, inasmuch as they are repeated, is therefore once again a variant of hysteresis, which in this case is the iteration of an act that is characterised by a competence not necessarily (indeed, only very rarely) accompanied by understanding. Both nature and technology as well as society operate by iteration much more than by understanding, which is why they are emerging structures and not the result of a divine or human construction that follows an intelligent design or some form of intentionality.
Becoming equals being iterated. What is iteration? Hegel wrote that meaning can only arise if something happens at least twice: ‘Einmal ist keinmal’, once is the same as never. For example, it could be a message sent by mistake, or containing an error, which is why when we subscribe to some service they ask us to confirm our email address. But, beyond this obvious practical function, iteration hides a metaphysical power that is not always taken into due account, and which acquires particular relevance at a time when technology, which is first of all iteration, has acquired unprecedented evidence, even though of course it has always been both in us and outside us, since we are intrinsically technological animals.
As we have seen, recording takes the place of causality. There could be causality without recording, but it would be nothing. If there is something, it is because there is recording, which from the logical, ontological and chronological point of view precedes causality, and moreover spares us the absurdity of the theories of some causa sui (‘cause of itself’). Recording is the ontological version of hysteresis, the principle of permanence of the substance as presence, resistance, existence. The realism I propose is not limited to believing in the existence of tables, chairs and anti-realist philosophers: as negative realism it recalls that reality resists thought; as positive realism it affirms that meaning comes from the world and its affordances; and as transcendental realism it affirms that the common root of resistance and affordance lies in recording. It is therefore necessary to start from here.
Being equals being recorded. If we follow the physical conjectures prevailing today – the Big Bang and its updated version, the Big Bounce – the origin of the universe presents itself as the weakening of an original recording. This original recording is the same currently found in black holes, which gave rise to space, time and spatial-temporal objects. These objects, after all, are characterised in ordinary experience as permanence and resistance, which find their condition of possibility in recording as the persistence of a state. From this point of view, being (i.e. the object of ontology) is the result of recording. Following an explosion, some very concentrated matter unfolded and became the world, which was a contingent fact. But in order for this contingency to emerge, transforming itself into the world, the explosion had to show not only the capacity to expand, but also the capacity to record, to keep track. At the beginning there was an explosion, at the end there will be thermal balance, and in the middle there is time, which tells the story of a growing tendency towards disorder and heat loss. But in each of these stages there is recording as the possibility of keeping track of the previous conditions, which, in the mesoscopic terms of our ordinary experience, defines the spatial-temporal characteristics of everyday objects (if the library behind me suddenly disappeared, I would have good reason to believe I was the victim of a hallucination, whether positive or negative).
