RESUMEN

BACKGROUND: Pelvic exenteration (PE) is often the only curative treatment option for selected locally advanced and locally recurrent colorectal cancer associated with significant morbidity. Open and laparoscopic approaches were accepted for this procedure. OBJECTIVE: This study aimed to examine the Chinese patient-reported outcomes (PROs) and health-related quality of life (HRQoL) after PE. METHODS: A total of 122 enrolled participants were asked to complete PROs at baseline and 1, 3, 6, 9 and 12 months after PE. PROs included seven symptoms from the National Cancer Institute's Patient-Reported Outcomes version of the Common Terminology Criteria for Adverse Events (PRO-CTCAE). The HRQoL was assessed using the Functional Assessment of Cancer Therapy-Colorectal (FACT-C). RESULTS: The overall postoperative complication rate was 41.0%. Patients experienced lower physical and functional well-being and FACT-C 1 month after surgery, then gradually recovered. The FACT-C score returned to baseline 9 months after surgery. Social and emotional well-being did not show signs of recovery until 6 months after the surgical procedure, and did not fully return to baseline until 12 months post-surgery. Symptom rates of insomnia, anxiety, discouragement, and sadness (composite score >0) did not improve significantly from baseline until 12 months after surgery. CONCLUSIONS: PE is a feasible treatment choice for locally advanced primary and recurrent colorectal cancer. Social, psychological, and emotional recovery in the Chinese population after PE tends to be slower compared with the physical condition.

RESUMEN

Community-based fact-checking is a promising approach to fact-check social media content at scale. However, an understanding of whether users trust community fact-checks is missing. Here, we presented n = 1,810 Americans with 36 misleading and nonmisleading social media posts and assessed their trust in different types of fact-checking interventions. Participants were randomly assigned to treatments where misleading content was either accompanied by simple (i.e. context-free) misinformation flags in different formats (expert flags or community flags), or by textual "community notes" explaining why the fact-checked post was misleading. Across both sides of the political spectrum, community notes were perceived as significantly more trustworthy than simple misinformation flags. Our results further suggest that the higher trustworthiness primarily stemmed from the context provided in community notes (i.e. fact-checking explanations) rather than generally higher trust towards community fact-checkers. Community notes also improved the identification of misleading posts. In sum, our work implies that context matters in fact-checking and that community notes might be an effective approach to mitigate trust issues with simple misinformation flags.

RESUMEN

PURPOSE: Androgen deprivation therapy (ADT) is a cornerstone treatment for advanced and metastatic prostate cancer. Real-world and patient-reported insights into ADT's impact on health-related quality of life (HRQoL) and communication experiences in healthcare settings remain underexplored. This patient organisation-initiated online survey aimed to assess these aspects. METHODS: Between December 2022 and August 2023, the patient organisation Think Blue Vlaanderen and the AZ Sint-Jan Hospital (Bruges, Belgium) invited ADT-treated patients to participate in a prospective, online, cross-sectional, patient-reported outcome survey. Demographic, clinical, HRQoL (FACT and EPIC-26), communication sources and information modality data were collected. Descriptive statistics and comparative analyses were applied. RESULTS: A total of 276/312 (88.5%) participating patients were on ADT at time of survey administration and completion, with the majority receiving a 3-monthly regimen. Sexual HRQoL was low and narrowly distributed (median (IQR): 16.7 (16.7-16.7)), with 84% of patients having erectile dysfunction (ED). Patients finding their ED problematic were more likely to seek pharmaceutical treatment. Hormonal HRQoL was widely distributed (median (IQR): 65 (45-85)), which improved with prolonged ADT duration. Physically active patients reported less lack of energy, but increased hot flashes. Within consistent FACT-G summary scores (median (IQR): 64.50 (54.75-77.00)), improved emotional wellbeing with prolonged ADT was noted. Multidisciplinary communication and multimodal information provision improved patient satisfaction. CONCLUSION: Patient organisation-initiated surveys offer real-world and patient-reported insights. Patient-tailored HRQoL assessments and longitudinal follow-up, physical activity, and multidisciplinary and multimodal communication approaches are warranted to improve patient-centred care in patients receiving ADT.

RESUMEN

In natural language processing, fact verification is a very challenging task, which requires retrieving multiple evidence sentences from a reliable corpus to verify the authenticity of a claim. Although most of the current deep learning methods use the attention mechanism for fact verification, they have not considered imposing attentional constraints on important related words in the claim and evidence sentences, resulting in inaccurate attention for some irrelevant words. In this paper, we propose a syntactic evidence network (SENet) model which incorporates entity keywords, syntactic information and sentence attention for fact verification. The SENet model extracts entity keywords from claim and evidence sentences, and uses a pre-trained syntactic dependency parser to extract the corresponding syntactic sentence structures and incorporates the extracted syntactic information into the attention mechanism for language-driven word representation. In addition, the sentence attention mechanism is applied to obtain a richer semantic representation. We have conducted experiments on the FEVER and UKP Snopes datasets for performance evaluation. Our SENet model has achieved 78.69% in Label Accuracy and 75.63% in FEVER Score on the FEVER dataset. In addition, our SENet model also has achieved 65.0% in precision and 61.2% in macro F1 on the UKP Snopes dataset. The experimental results have shown that our proposed SENet model has outperformed the baseline models and achieved the state-of-the-art performance for fact verification.

RESUMEN

PURPOSE: This study aimed to examine health-related quality of life (HRQoL) in head and neck cancer patients at 1 and 5 years after successful treatment of their tumors, and to explore the usefulness of 2 instruments for assessing the need of dental care services. METHODS: This cross-sectional pilot study included 20 adult patients with head and neck cancer who completed the Functional Assessment of Cancer Therapy-Head and Neck (FACT H&N) Symptom Index and the European Organization for Research and Treatment of Cancer Quality of Life Head and Neck Module (EORTC QLQ-H&N43) after 1 and 5 years of treatment. RESULTS: Mean (standard deviation, SD) scores of the FACT H&N Symptom Index were higher (better HRQoL) at 5 years than at 1 year (24.1 [4.4] vs. 21.1 [6.4]; p = 0.236). Only three of the ten items of FACT H&N (swallow, pain in mouth/throat or neck, and solid foods) evaluated oral health. In the EORTC QLQ-H&N43 questionnaire, scores were lower at 5 years (better HRQoL) in almost all multi- and single-item symptoms. This questionnaire includes four multi-item scales (pain in the mouth, social eating, swallowing, and problems with teeth) measuring dental and orthodontic needs. CONCLUSION: HRQoL in patients with head and neck cancer improved with the length of follow-up. The EORTC QLQ-H&N43 has more items addressing oral health compared to the FACT H&N Symptom Index and may be more adequate to assess the need of dental therapy in clinical practice.

RESUMEN

Chromatin condensation state is the key for retrieving genetic information. High-mobility group protein (HMG) proteins exhibit DNA-binding and bending activities, playing an important role in the regulation of chromatin structure. We have shown that nucleosomes tightly packaged into heterochromatin undergo considerable dynamic histone H2A-H2B maintenance via the direct interaction between HP1/Swi6 and facilitate chromatin transcription (FACT), which is composed of the Spt16/Pob3 heterodimer and Nhp6. In this study, we analyzed the role of Nhp6, an HMG box protein, in the FACT at heterochromatin. Pob3 mutant strains showed derepressed heterochromatin-dependent gene silencing, whereas Nhp6 mutant strains did not show significant defects in chromatin regulation or gene expression, suggesting that these two modules play different roles in chromatin regulation. We expressed a protein fusing Nhp6 to the C-terminus of Pob3, which mimics the multicellular FACT component Ssrp1. The chromatin-binding activity of FACT increased with the number of Nhp6 fused to Pob3, and the heterochromatin formation rate was promoted more strongly. Furthermore, we demonstrated that this promotion of heterochromatinization inhibited the heterochromatic variegation caused by epe1+ disruption. Heterochromatic variegation can be observed in a variety of regulatory steps; however, when it is caused by fluctuations in chromatin arrangement, it can be eliminated through the strong recruitment of the FACT complex.

RESUMEN

As a novel technology for fabricating large-screen OLED devices, OLED inkjet printing places extreme demands on the positioning accuracy of inkjet printing platforms. However, thermal deformation of the connection mechanism often reduces the printing precision of OLED printing equipment, significantly impacting overall print quality. This study introduces a compliant connection mechanism that achieves precise positioning of the inkjet printing platform and can self-eliminate thermal distortion. The design of the mechanism's core component is based on the Freedom and Constraint Topology (FACT) principle. This component is constructed from three distinct compliant sections arranged in series, collectively providing three degrees of freedom. Furthermore, the resistance to deformation caused by gravity and other external forces was evaluated by analyzing both vertical and horizontal stiffness. To validate the mechanism's thermal distortion elimination and gravity resistance capabilities, finite element analysis (FEA) was carried out. The results demonstrate that the mechanism effectively reduces the maximum deformation of the platform by approximately 46% and the average deformation across the entire platform by approximately 59%. These findings confirm that the mechanism has potential in high-precision positioning tasks that need to mitigate thermal distortion.

RESUMEN

Facilitates chromatin transcription (FACT) is a histone chaperone that supports transcription through chromatin in vitro, but its functional roles in vivo remain unclear. Here, we analyze the in vivo functions of FACT with the use of multi-omics analysis after rapid FACT depletion from human cells. We show that FACT depletion destabilizes chromatin and leads to transcriptional defects, including defective promoter-proximal pausing and elongation, and increased premature termination of RNA polymerase II. Unexpectedly, our analysis revealed that promoter-proximal pausing depends not only on the negative elongation factor (NELF) but also on the +1 nucleosome, which is maintained by FACT.

RESUMEN

Systematic functional profiling of the gene set that directs embryonic development is an important challenge. To tackle this challenge, we used 4D imaging of C. elegans embryogenesis to capture the effects of 500 gene knockdowns and developed an automated approach to compare developmental phenotypes. The automated approach quantifies features-including germ layer cell numbers, tissue position, and tissue shape-to generate temporal curves whose parameterization yields numerical phenotypic signatures. In conjunction with a new similarity metric that operates across phenotypic space, these signatures enabled the generation of ranked lists of genes predicted to have similar functions, accessible in the PhenoBank web portal, for ∼25% of essential development genes. The approach identified new gene and pathway relationships in cell fate specification and morphogenesis and highlighted the utilization of specialized energy generation pathways during embryogenesis. Collectively, the effort establishes the foundation for comprehensive analysis of the gene set that builds a multicellular organism.

RESUMEN

This study aimed to evaluate a new service model, Specialists Together In the Community (STIC), in terms of patient outcomes. This model integrates Flexible Assertive Community Treatment (FACT)-principles with expertise of specialized teams that offer diagnosis-related outpatient treatment. In a pre-post design, symptoms and quality of life of 930 former FACT-patients were measured repeatedly pre- and post-STIC. Regarding patients in former specialized teams, pre- and post-treatment social functioning and symptoms were measured for the pre- (n = 944) and post-STIC (n = 544) groups. Against expectation, symptoms of former FACT-patients remained stable post-STIC compared to a slight decrease pre-STIC. According to expectation, pre- and post-STIC groups had an equal symptom reduction. Unexpectedly, the post-STIC group did not improve more on social functioning than the pre-STIC group. Explorative analysis showed less treatment contacts in the post-STIC group. The highly similar patient outcomes post-STIC could be improved by monitoring process outcomes and prolonging study duration.

RESUMEN

Introduction: In response to the increasing demand for long-term care services for older people, the Chinese government has launched a pilot program for long-term care insurance (LTCI) since 2016. The objective of this study is to evaluate the performance and effectiveness of this program in China and provide recommendations for the future development and expansion of the LTCI system. Methods: We developed a comprehensive evaluation framework to assess these LTCI policies implemented in all 49 pilot cities in China. Results: Based on our evaluation, the average assessment score for the LTCI program across all pilot cities was 71.8 points, with scores ranging from 57.5 to 92.5 points in these cities. Furthermore, most of the pilot cities achieved higher scores in the fact-based assessment compared to the value-based assessment. Discussion: The results suggested that the overall pilot effect regarding LTCI was favorable, but there were significant regional disparities. Moreover, in most of pilot cities, current LTCI policies were designed to alleviate both the financial burden and the burden of caring for people with disabilities that families faced. However, some challenges still remained, such as the lack of community and home-based care services, the need to expand the coverage of insurance, and the importance of diversifying funding sources.

RESUMEN

Immune thrombotic thrombocytopenic purpura (iTTP) is a rare and potentially life-threatening disorder. Treatment advances have lowered morbidity rates, but past acute events can still cause long-term consequences, reducing health-related quality of life (HRQoL) and determining cognitive impairment, anxiety, and depression. We aimed to investigate these aspects and the role of caplacizumab and rituximab: 39 patients were evaluated using the Medical Outcomes Study 36-Item Short Form Health Survey (SF-36), the FACIT-Fatigue, the Hospital Anxiety and Depression Scale, and the Functional Assessment in Cancer Therapy-Cognitive Function questionnaires. The median age at study inclusion was 50 years (IQR 38-60), and the median follow-up from diagnosis was 97 months (IQR 14-182); 82% of patients were female, and 36% had one or more recurrences. Caplacizumab was administered in 16 patients (41%), as well as rituximab. ITTP patients reported lower physical and mental HRQoL scores than the general population. No differences in physical or mental domains were observed between patients treated or not with caplacizumab, while those who received rituximab reported lower scores in mental health. Neurological impairment at diagnosis correlated with worse fatigue. The majority of patients (72%) reported anxiety or depression (82%). ITTP had a significant impact on the long-term cognitive function, fatigue, depression, and anxiety levels of patients, with a negative effect on their HRQoL. Our findings underscore the need to pay special attention to patients' long-term physical and mental health, regardless of the medical treatments received.

RESUMEN

The aim of this article is to carry out a sociological-conceptual genealogy of the evolutionist perspective (non-teleological) of approaching social reality. While during the first phases of modernity, a teleological and progressive conception of evolution was imposed, clearly manifested in the proposals of Auguste Comte or Herbert Spencer, in the last decades important bifurcations, processes, and developments have emerged that question the linearity and the finalist character of these positions. We consider that these approaches are closer to the nature of change and social phenomena, so it seems important to us to analyze some of the most outstanding contributions-in the form of sociological genealogy, as we have already mentioned-that have developed this perspective. In order to carry out our task, we have organized four sections: In the first, we make a critique of the sociological evolutionism represented by Comte, Spencer, and Parsons, focusing on the limits of their proposals and the blind spots associated with them. Second, we will analyze the anti-teleological cognitive approaches of Donald and the importance they attach to cultural transmission as a key element for understanding the evolution of both cognition and human societies. In a third moment, we will analyze the coexistence in Weber's work between the dynamics of 'disenchantment' and 're-enchantment' of the world in modern societies, understood as the two sides of the same coin that are in constant dynamic tension and that break with the evolutionary vision that goes from magic through religion to science, or from belief to knowledge. In a fourth moment, we analyze the relevance of approaches focused on what we have called 'multiple evolutions' (plural) that collide with each other-the conflicting simultaneity of the non-simultaneous-of their rhythms and directions, inspired by the works of Knöbl, Koselleck, Luhmann, Rosa, Eisenstadt, Abbott, and Zerubavel, which pave the way for the construction of a non-teleological approach to evolution.

RESUMEN

The spread of fake news on social media is a pressing issue. Here, we develop a mathematical model on social networks in which news sharing is modeled as a coordination game. We use this model to study the effect of adding designated individuals who sanction fake news sharers (representing, for example, correction of false claims or public shaming of those who share such claims). By simulating our model on synthetic square lattices and small-world networks, we demonstrate that social network structure allows fake news spreaders to form echo chambers and more than doubles fake news' resistance to distributed sanctioning efforts. We confirm our results are robust to a wide range of coordination and sanctioning payoff parameters as well as initial conditions. Using a Twitter network dataset, we show that sanctioners can help contain fake news when placed strategically. Furthermore, we analytically determine the conditions required for peer sanctioning to be effective, including prevalence and enforcement levels. Our findings have implications for developing mitigation strategies to control misinformation and preserve the integrity of public discourse.

RESUMEN

Acoustic neuroma excision in patients with cerebellopontine angle (CPA) tumours offers particular rehabilitation problems due to the complicated architecture of the cerebellum and brainstem tissues involved. CPA tumours (acoustic neuromas) are slow-growing tumours that arise from the vestibulocochlear nerve. Surgical excision of these tumours can cause neurological abnormalities that compromise motor coordination, balance, and facial nerve function. The case study emphasises the importance of a comprehensive physiotherapeutic approach in rehabilitating a patient following acoustic neuroma excision, with a focus on particular CPA tumour deficits. The rehabilitation programme focuses on improving functional outcomes through balance, proprioception, and vestibular rehabilitation that is customised to the demands and deficiencies of the patient. Our comprehensive approach seeks to improve patients' quality of life, promote neurological healing, and support easy reintegration into normal activities following CPA tumour surgery.

RESUMEN

Specific learning disorder (SLD) is a neurodevelopmental disorder that affects 5-15% of school-aged children worldwide. Often, difficulties in reading (SLD-RD) and mathematics (SLD-MD) occur together. Deficits in phonological awareness (PA) have been identified as the common factor between the two difficulties. Intervention in PA has been shown to be effective in SLD-RD; however, it is not clear whether it is also effective in SLD-MD. Neuropsychological intervention is usually conducted face-to-face, but when the patient is in a remote location or during extraordinary situations such as the COVID-19 pandemic, tele neuropsychology (TeleNP) may be a suitable alternative. The objective of this study was to evaluate the efficacy of a telerehabilitation program for PA to improve math skills in children with SLD-RD/SLD-MD. The study had an N-of-1 SCED design, and included six children aged 10-12 years with SLD-RD/SLD-MD. After four baseline measurements with an arithmetic verification paradigm, they were treated with TeleNP-PA. The effect on each participant was evaluated using visual analysis and the reliable change index. After the intervention, all participants showed improvement in arithmetic tasks, suggesting that the PA intervention had a positive influence on these skills.

RESUMEN

Background: The 2023 Obesity Fact Sheet aims to present an updated overview of obesity prevalence across all age groups, including children and adolescents. Methods: This study included individuals aged ≥20 years (n=16,941,423 in 2021) who underwent health checkups provided by the Korean National Health Insurance Service between 2012 and 2021. The prevalence of obesity and abdominal obesity was standardized by age and sex using data from the 2010 population and housing census. For children and adolescents (6 to 18 years) (n=884 in 2021), we used the Korea National Health and Nutrition Examination Survey (2012 to 2021), and obesity was defined by the corresponding sex- and age-specific body mass index percentile of 95th or greater based on the 2017 Korean National Growth Chart for Children and Adolescents. Results: The overall prevalence of obesity in 2021 is 38.4% (49.2% in men and 27.8% in women), which is a 1.27-fold increase from 30.2% in 2012. The prevalence of obesity has increased across all age groups, particularly among those aged 20, 30, and 80 years. The prevalence of class III obesity substantially increased from 0.35% (men) and 0.42% (women) in 2012 to 1.21% and 0.97% in 2021, with 3.46- and 2.31-fold increases, respectively. This increase was particularly pronounced in young adults. The prevalence of obesity in children and adolescents has surged from 9.7% in 2012 to 19.3% in 2021, with a greater increase among boys. Conclusion: Our study provides information on the current status of obesity prevalence based on the 2023 Obesity Fact Sheet, emphasizing the urgency of implementing timely strategies to reverse this increasing trend.

RESUMEN

Background Due to earlier detection and improved treatment and examinations, there has been a rise in the survival rate of patients with breast cancer (BC). It is imperative to examine the health-related quality of life (QoL) of these patients, as it can aid healthcare professionals and authorities in comprehending the variables that influence quality of life. Unfortunately, there is a dearth of information on the subject of women in Nineveh. In Nineveh, a study sought to delve into the quality of life experienced by women undergoing treatment or on follow-up for breast cancer at Mosul Oncology and Nuclear Medicine Hospital. Specifically, researchers wanted to see how age and treatment impacted the QoL of these women. Methods A cross-sectional study was conducted on 212 women with BC. Clinico-pathological-, social-, disease-, and treatment-related characteristics were reviewed. The Functional Assessment of Cancer Therapy-Breast (FACT-B) questionnaire was used for assessing QoL in this study. Results The overall FACT-B score was 75.7 (SD=19.99). Around 36.3% (n=77) of women with BC suffered from a lack of energy, and 39% (n=83) could not meet the needs of their families. The mean score of emotional well-being was the lowest among the FACT-B subscales. Patients aged 60 years and older had significantly worse QoL than younger patients (less than 60 years), and patients receiving chemotherapy had poor QoL. During the chemotherapy period, 51.4% (n=77) of patients were bothered by the side effects of treatment; 43.8% (n=65) suffered from pain; 35.3% (n=53) had nausea; and 39.1% (n=58) felt ill. Conclusions Patients with breast carcinoma who are older tend to experience a lower quality of life, according to the findings of a recent study. Interestingly, those who undergo systemic chemotherapy have a worse QoL than their counterparts who complete their chemotherapy cycles. As a result, healthcare providers must offer targeted interventions to improve quality of life, particularly for those who fall into the older age group and those receiving chemotherapy.

RESUMEN

Automated fact-checking, using machine learning to verify claims, has grown vital as misinformation spreads beyond human fact-checking capacity. Large language models (LLMs) like GPT-4 are increasingly trusted to write academic papers, lawsuits, and news articles and to verify information, emphasizing their role in discerning truth from falsehood and the importance of being able to verify their outputs. Understanding the capacities and limitations of LLMs in fact-checking tasks is therefore essential for ensuring the health of our information ecosystem. Here, we evaluate the use of LLM agents in fact-checking by having them phrase queries, retrieve contextual data, and make decisions. Importantly, in our framework, agents explain their reasoning and cite the relevant sources from the retrieved context. Our results show the enhanced prowess of LLMs when equipped with contextual information. GPT-4 outperforms GPT-3, but accuracy varies based on query language and claim veracity. While LLMs show promise in fact-checking, caution is essential due to inconsistent accuracy. Our investigation calls for further research, fostering a deeper comprehension of when agents succeed and when they fail.

RESUMEN

Background: The Functional Assessment of Cancer Therapy-General (FACT-G) is a widely used quality-of-life measure. However, no studies have examined the FACT-G among patients with life-limiting illnesses who present to emergency departments (EDs). Objective: The goal of this study was to examine the psychometric properties of the FACT-G among patients with life-limiting illnesses who present to EDs in the United States. Methods: This cross-sectional study pooled data from 12 EDs between April 2018 and January 2020 (n = 453). Patients enrolled in the study were adults with one or more of the four life-limiting illnesses: advanced cancer, Congestive Heart Failure, Chronic Obstructive Pulmonary Disease, or End-Stage Renal Disease. We conducted item, exploratory, and confirmatory analyses (exploratory factor analysis [EFA] and confirmatory factor analysis [CFA]) to determine the psychometric properties of the FACT-G. Results: The FACT-G had good internal consistency (Cronbach's alpha α = 0.88). The simplest EFA model was a six-factor structure. The CFA supported the six-factor structure, evidenced by the adequate fit indices (comparative fit index = 0.93, Tucker-Lewis index = 0.92, root-mean-square error of approximation = 0.05; 90% confidence interval: 0.04 - 0.06). The six-factor structure comprised the physical, emotional, work and daily activities-related functional well-being, and the family and friends-related social well-being domains. Conclusions: The FACT-G is a reliable measure of health-related quality of life among patients with life-limiting illnesses who present to the ED. Clinical Trial Registration: NCT03325985.
