RESUMO

BACKGROUND: Dyslipidemia management is a cornerstone in cardiovascular disease prevention and relies heavily on patient adherence to lifestyle modifications and medications. Numerous cholesterol patient education materials are available online, but it remains unclear whether these resources are suitable for the majority of North American adults given the prevalence of low health literacy. This review aimed to (1) identify printable cholesterol patient education materials through an online search, and (2) evaluate the readability, understandability, and actionability of each resource to determine its utility in practice. METHODS AND RESULTS: We searched the MEDLINE database for peer-reviewed educational materials and the websites of Canadian and American national health organizations for gray literature. Readability was measured using the Flesch-Kincaid Grade Level, and scores between fifth- and sixth-grade reading levels were considered adequate. Understandability and actionability were scored using the Patient Education Materials Assessment Tool and categorized as superior (>80%), adequate (50%-70%), or inadequate (<50%). Our search yielded 91 results that were screened for eligibility. Among the 22 educational materials included in the study, 15 were identified through MEDLINE, and 7 were from websites. The readability across all materials averaged an 11th-grade reading level (Flesch-Kincaid Grade Level=11.9±2.59). The mean±SD understandability and actionability scores were 82.8±6.58% and 40.9±28.60%, respectively. CONCLUSIONS: The readability of online cholesterol patient education materials consistently exceeds the health literacy level of the average North American adult. Many resources also inadequately describe action items for individuals to self-manage their cholesterol, representing an implementation gap in cardiovascular disease prevention.

RESUMO

Enhanced health literacy in children has been empirically linked to better health outcomes over the long term; however, few interventions have been shown to improve health literacy. In this context, we investigate whether large language models (LLMs) can serve as a medium to improve health literacy in children. We tested pediatric conditions using 26 different prompts in ChatGPT-3.5, ChatGPT-4, Microsoft Bing, and Google Bard (now known as Google Gemini). The primary outcome measurement was the reading grade level (RGL) of output as assessed by Gunning Fog, Flesch-Kincaid Grade Level, Automated Readability Index, and Coleman-Liau indices. Word counts were also assessed. Across all models, output for basic prompts such as "Explain" and "What is (are)," were at, or exceeded, the tenth-grade RGL. When prompts were specified to explain conditions from the first- to twelfth-grade level, we found that LLMs had varying abilities to tailor responses based on grade level. ChatGPT-3.5 provided responses that ranged from the seventh-grade to college freshmen RGL while ChatGPT-4 outputted responses from the tenth-grade to the college senior RGL. Microsoft Bing provided responses from the ninth- to eleventh-grade RGL while Google Bard provided responses from the seventh- to tenth-grade RGL. LLMs face challenges in crafting outputs below a sixth-grade RGL. However, their capability to modify outputs above this threshold, provides a potential mechanism for adolescents to explore, understand, and engage with information regarding their health conditions, spanning from simple to complex terms. Future studies are needed to verify the accuracy and efficacy of these tools.

RESUMO

The literature has confirmed that when managers increase profits through earnings management, the readability of annual reports may be reduced Lo (2017), Ye (2018). Whether this conclusion is suitable for Chinese corporate social responsibility (CSR) reports, however, is still unclear. Based on the panel data of 5083 Chinese non-financial listed companies from 2010 to 2019, this paper adopts multiple linear regression to investigate the impact of earnings management on the readability of Chinese CSR reports. The results show that: (1) There is a significant negative correlation between earnings management and the readability of Chinese CSR reports, with the readability of Chinese annual reports as a mediating variable. (2) The negative effect is more significant when companies are not punished for violations, when the internal control index is low, when companies lack ISO14001 certification and when companies do not have independent third-party authentication for Chinese CSR reports. (3) When earnings management just exceeds zero, the readability of Chinese CSR reports decreases. (4) The economic consequences of reducing the readability of Chinese CSR reports are that financing costs are increased and environmental performance is decreased. To improve the quality of information disclosure of listed companies, the recommendations are as follows: First, the government should issue CSR reporting standards to reduce the manipulation of Chinese CSR reports. Second, Chinese CSR reports disclosed by listed companies must be audited by independent third parties to enhance the credibility of the information. Third, the company needs to strengthen its external and internal supervision to reduce the manipulation space for the readability of Chinese CSR reports. This study extends the negative relationship between earnings management and the readability from annual reports to Chinese CSR reports. To prevent investors from detecting earnings management, the readability of Chinese CSR reports may be reduced. At the same time, the study has definitely added value to the existing literature in the domain of CSR.

RESUMO

Language processing can be measured objectively using late components in the evoked brain potential. The most established component in this area of research is the N400 component, a negativity that peaks at about 400 ms after stimulus onset with a centro-parietal maximum. It reflects semantic processing. Its presence, as well as its temporal and quantitative expression, allows to conclude about the quality of processing. It is therefore suitable for measuring speech comprehension in special populations, such as cochlear implant (CI) users. The following is an overview of the use of the N400 component as a tool for studying language processes in CI users. We present studies with adult CI users, where the N400 reflects the quality of speech comprehension with the new hearing device and we present studies with children where the emergence of the N400 component reflects the acquisition of their very first vocabulary.

RESUMO

Supercritical carbon dioxide (SC-CO2) has emerged as a nonthermal technology to guarantee food safety. This review addresses the potential of SC-CO2 technology in food preservation, discussing the microbial inactivation mechanisms and the impact on food products' quality parameters and bioactive compounds. Furthermore, the main advantages and gaps are denoted. SC-CO2 technology application causes adequate microbial reductions (>5 log cfu/mL) of spoilage and pathogenic microorganisms, enzyme inactivation, and improvements in the storage stability in fruit and vegetable products (mainly fruit juices), meat products, and dairy derivatives. SC-CO2-treated products maintain the physicochemical, technological, and sensory properties, bioactive compound concentrations, and biological activity (antioxidant and angiotensin-converting enzyme-inhibitory activities) similar to the untreated products. The optimization of processing parameters (temperature, pressure, CO2 volume, and processing times) is mandatory for achieving the desired results. Further studies should consider the expansion to different food matrices, shelf-life evaluation, bioaccessibility of bioactive compounds, and in vitro and in vivo studies to prove the benefits of using SC-CO2 technology. Moreover, the impact on sensory characteristics and, mainly, the consumer perception of SC-CO2-treated foods need to be elucidated. We highlight the opportunity for studies in postbiotic production. In conclusion, SC-CO2 technology may be used for microbial inactivation to ensure food safety without losing the quality parameters.

RESUMO

Background: In an era wherein, persuasive evidence continues to witness the association between systemic and periodontal diseases, the absence of scientific data on dental professionals' comprehension concerning the HIV infection and periodontal link is lamentably backward. Thus, the key objective of this research is to ascertain the extent of comprehension possessed by dentists and dental hygienists concerning periodontal implications and their management in HIV patients. Methods: It is a quantitative cross-sectional survey employing a descriptive approach focusing on a specific cohort of dental professionals. The study setting featured an online platform for the distribution of concealed, closed-ended, structured questionnaire. The data was gathered for four sections: six comprehension statements about periodontal manifestations in HIV patients; fifteen comprehension statements about HIV patients' periodontal management; eight familiarity statements about HIV management; and two educational statements about HIV. The comparisons of comprehension scores were drawn between variables such as specialties, age groups, and genders. Results: The survey represented 468 dental professionals representing distinct dental specialties, with a mean age of 24.26 ± 7.53 years. The mean comprehension score for all groups of participants is 10.31 ± 9.34 (33.25%). The highest scores were recorded among those aged 31-40 (20.67 ± 8.31), followed by those aged 40+ (19.38 ± 9.39), 20-30 (9.53 ± 8.96), and under 20 (8.92 ± 8.57), at p < 0.001. The female participants (15.06 ± 12.2) exhibited substantially better scores in contrast to the male participants (8.74 ± 7.57). Periodontists (27.77 ± 3.08) comprehended most, then the oral medicine practitioners (25 ± 0). Dental hygiene students (5.52 ± 3.56) and hygienists (7.67 ± 9.72) comprehended the least. The scores for all four domains assessed were disappointingly low: knowledge about HIV-periodontal manifestations (2.81 ± 2.18), knowledge about management of periodontal diseases in HIV patients (3.73 ± 4.7), familiarity with periodontal care in HIV patients (2.87 ± 3.01), and education received about HIV and periodontal diseases (0.91 ± 0.66). Conclusion: Dental professionals are notably incomprehensive, unfamiliar, and lacking in expertise in the realm of periodontal facets of HIV. The periodontists and oral medicine practitioners showed a substantial amount of comprehension, while the dental hygiene students and dental hygienists presented a conspicuously inadequate level of comprehension. The study outcome could potentially serve as an invaluable instrument for self-assessment by dental professionals and educators. HIV/AIDS ought not to persist as an unspoken taboo or disregarded subject within the dental field, particularly in periodontics, but rather should receive prominence in dental schools and professional development programs.

RESUMO

OBJECTIVES: To assess the quality and accuracy of information contained within the websites of providers of marketed orthodontic products. MATERIALS AND METHODS: Twenty-one websites of orthodontic appliance and adjunct (product) providers were identified. The website content was assessed via two validated quality-of-information instruments (DISCERN and the Journal of the American Medical Association [JAMA] benchmarks) and an accuracy-of-information instrument. Website content was qualitatively analyzed for themes and subthemes. RESULTS: More than half (n = 11; 52.3%) of the assessed websites contained clinician testimonials. The mean (SD) DISCERN score was 33.14 (5.44). No website recorded the minimum of three JAMA benchmarks required to indicate reliability. The most common content themes related to quality-of-life impact and treatment duration. Just 8% of the statements within the websites were objectively true. The Pearson correlation coefficient indicated that the DISCERN scores were correlated with the accuracy-of-information scores (r = .83; P < .001). CONCLUSIONS: The quality and accuracy of information contained within the websites of the providers of marketed orthodontic products was poor. The combined use of DISCERN and the accuracy-of-information instrument may help overcome the shortcomings of each. Clinicians should check the accuracy of information on orthodontic product provider websites before adding links to those websites on their own sites.

RESUMO

Wearable sensors utilize changes in color as a response to physiological stimuli, making them easily recognizable by the naked eye. These colorimetric wearable sensors offer benefits such as easy readability, rapid responsiveness, cost-effectiveness, and straightforward manufacturing techniques. However, their applications in detecting volatile organic compounds (VOCs) in situ have been limited due to the low concentration of complex VOCs and complicated external interferences. Aiming to address these challenges, we introduced readable and wearable colorimetric sensing arrays with a microchannel structure and highly gas-sensitive materials for in situ detection of complex VOCs. The highly gas-sensitive materials were designed by loading gas-sensitive dyes into the porous metal-organic frameworks and further depositing the composites on the electrospun nanofiber membrane. The colorimetric sensor arrays were fabricated using various gas-sensitive composites, including eight dye/MOF composites that respond to various VOCs and two Pd2+/dye/MOF composites that respond to ethylene. This enables the specific recognition of multiple characteristic VOCs. A microfluidic channel made of polydimethylsiloxane (PDMS) was integrated with different colorimetric elements to create a wearable sensor array. It was attached to the surface of fruits to collect and monitor VOCs using the DenseNet classification method. As a proof of concept, we demonstrated the feasibility of the wearable sensing system in monitoring the ripening process of fruits by continuously measuring the VOC emissions from the skin of the fruit.

RESUMO

Linguistic communication requires interlocutors to consider differences in each other's knowledge (perspective-taking). However, perspective-taking might either be spontaneous or strategic. We monitored listeners' eye movements in a referential communication task. A virtual speaker gave temporally ambiguous instructions with scalar adjectives ("big" in "big cubic block"). Scalar adjectives assume a contrasting object (a small cubic block). We manipulated whether the contrasting object (a small triangle) for a competitor object (a big triangle) was in common ground (visible to both speaker and listener) or was occluded so it was in the listener's privileged ground, in which case perspective-taking would allow earlier reference-resolution. We used a complex visual context with multiple objects, making strategic perspective-taking unlikely when all objects are in the listener's referential domain. A turn-taking, puzzle-solving task manipulated whether participants could anticipate a more restricted referential domain. Pieces were either confined to a small area (requiring fine-grained coordination) or distributed across spatially distinct regions (requiring only coarse-grained coordination). Results strongly supported spontaneous perspective-taking: Although comprehension was less time-locked in the coarse-grained condition, participants in both conditions used perspective information to identify the target referent earlier when the competitor contrast was in privileged ground, even when participants believed instructions were computer-generated.

RESUMO

A core aspect of human speech comprehension is the ability to incrementally integrate consecutive words into a structured and coherent interpretation, aligning with the speaker's intended meaning. This rapid process is subject to multidimensional probabilistic constraints, including both linguistic knowledge and non-linguistic information within specific contexts, and it is their interpretative coherence that drives successful comprehension. To study the neural substrates of this process, we extract word-by-word measures of sentential structure from BERT, a deep language model, which effectively approximates the coherent outcomes of the dynamic interplay among various types of constraints. Using representational similarity analysis, we tested BERT parse depths and relevant corpus-based measures against the spatiotemporally resolved brain activity recorded by electro-/magnetoencephalography when participants were listening to the same sentences. Our results provide a detailed picture of the neurobiological processes involved in the incremental construction of structured interpretations. These findings show when and where coherent interpretations emerge through the evaluation and integration of multifaceted constraints in the brain, which engages bilateral brain regions extending beyond the classical fronto-temporal language system. Furthermore, this study provides empirical evidence supporting the use of artificial neural networks as computational models for revealing the neural dynamics underpinning complex cognitive processes in the brain.

RESUMO

This study investigated the relationship between autistic traits, expressiveness, readability (both actual and perceived), social favourability, and likability. Sixty participants designated as 'targets' were video recorded in a range of social scenarios and their autistic traits were measured using the Autism Spectrum Quotient. The videos were then shown to 106 new participants designated 'perceivers', who were split into three groups to make judgments related to readability, expressiveness, and social favourability respectively. Mediation analyses revealed that autistic traits negatively impacted both perceived likeability and social favourability, mediated by lowered expressiveness. Autistic traits also directly impacted readability, which was not mediated by expressiveness. The findings show how the level of autistic traits of a target can influence how they are socially perceived by others.

RESUMO

BACKGROUND: High rates of posthospitalization errors are observed in children with medical complexity (CMC). Poor parent comprehension of and adherence to complex discharge instructions can contribute to errors. Pediatrician views on common barriers and facilitators to parent comprehension and adherence are understudied. OBJECTIVE: To examine pediatrician perspectives on barriers and facilitators experienced by parents in comprehension of and adherence to inpatient discharge instructions for CMC. DESIGN, SETTINGS, AND PARTICIPANTS: We conducted a qualitative, descriptive study of attending pediatricians (n = 20) caring for CMC in inpatient settings (United States and Canada) and belonging to listservs for pediatric hospitalists/complex care providers. We used purposive/maximum variation sampling to ensure heterogeneity (e.g., hospital, region). MAIN OUTCOME AND MEASURES: A multidisciplinary team designed and piloted a semistructured interview guide with pediatricians who care for CMC. Team members conducted semistructured interviews via phone or video call. Interviews were audiorecorded and transcribed. We analyzed transcripts using content analysis; codes were derived a priori from a conceptual framework (based on the Pediatric Self-Management Model) and a preliminary transcript analysis. We applied codes and identified emerging themes. RESULTS: Pediatricians identified three themes as barriers and facilitators to discharge instruction comprehension and adherence: (1) regimen complexity, (2) access to the healthcare team (e.g., inpatient team, outpatient pediatrician, home nursing) and resources (e.g., medications, medical equipment), and (3) need for a family centered and health literacy-informed approach to discharge planning and education. Next steps include the assessment of parent perspectives on barriers and facilitators to discharge instruction comprehension and adherence for prents of CMC and the development of intervention strategies.

RESUMO

This cross-sectional study compared plain language summaries (PLSs) from medical and non-medical organizations regarding conclusiveness, readability and textual characteristics. All Cochrane (medical PLSs, n = 8638) and Campbell Collaboration and International Initiative for Impact Evaluation (non-medical PLSs, n = 163) PLSs of latest versions of systematic reviews published until 10 November 2022 were analysed. PLSs were classified into three conclusiveness categories (conclusive, inconclusive and unclear) using a machine learning tool for medical PLSs and by two experts for non-medical PLSs. A higher proportion of non-medical PLSs were conclusive (17.79% vs 8.40%, P < 0.0001), they had higher readability (median number of years of education needed to read the text with ease 15.23 (interquartile range (IQR) 14.35 to 15.96) vs 15.51 (IQR 14.31 to 16.77), P = 0.010), used more words (median 603 (IQR 539.50 to 658.50) vs 345 (IQR 202 to 476), P < 0.001). Language analysis showed that medical PLSs scored higher for disgust and fear, and non-medical PLSs scored higher for positive emotions. The reason for the observed differences between medical and non-medical fields may be attributed to the differences in publication methodologies or disciplinary differences. This approach to analysing PLSs is crucial for enhancing the overall quality of PLSs and knowledge translation to the general public.

RESUMO

Accessible, accurate information, and readability play crucial role in empowering individuals managing osteoporosis. This study showed that the responses generated by ChatGPT regarding osteoporosis had serious problems with quality and were at a level of complexity that that necessitates an educational background of approximately 17 years. PURPOSE: The use of artificial intelligence (AI) applications as a source of information in the field of health is increasing. Readable and accurate information plays a critical role in empowering patients to make decisions about their disease. The aim was to examine the quality and readability of responses provided by ChatGPT, an AI chatbot, to commonly asked questions regarding osteoporosis, representing a major public health problem. METHODS: "Osteoporosis," "female osteoporosis," and "male osteoporosis" were identified by using Google trends for the 25 most frequently searched keywords on Google. A selected set of 38 keywords was sequentially inputted into the chat interface of the ChatGPT. The responses were evaluated with tools of the Ensuring Quality Information for Patients (EQIP), the Flesch-Kincaid Grade Level (FKGL), and the Flesch-Kincaid Reading Ease (FKRE). RESULTS: The EQIP score of the texts ranged from a minimum of 36.36 to a maximum of 61.76 with a mean value of 48.71 as having "serious problems with quality." The FKRE scores spanned from 13.71 to 56.06 with a mean value of 28.71 and the FKGL varied between 8.48 and 17.63, with a mean value of 13.25. There were no statistically significant correlations between the EQIP score and the FKGL or FKRE scores. CONCLUSIONS: Although ChatGPT is easily accessible for patients to obtain information about osteoporosis, its current quality and readability fall short of meeting comprehensive healthcare standards.

RESUMO

BACKGROUND: This study aimed to evaluate the content, reliability, quality and readability of information on Internet websites about early orthodontic treatment. METHODS: The "early orthodontic treatment" search term was individually entered into four web search engines. The content quality and reliability were reviewed with DISCERN, Journal of American Medical Association (JAMA), and Health on the Net code (HONcode) tools using the contents of websites meeting predetermined criteria. The readability of websites was evaluated with Flesch Reading Facilitate Score (FRES) and Flesch-Kincaid Grade Level (FKGL). RESULTS: Eighty-six websites were suitable for inclusion and scoring of the 200 websites. 80.2% of websites belonged to orthodontists, 15.1% to multidisciplinary dental clinics and 4.7% to professional organizations. The mean DISCERN score of all websites (parts 1 and 2) was 27.98/75, ranging between 19 and 67. Professional organization websites had the highest scores for DISCERN criteria. Moreover, 45.3% of websites were compatible with JAMA's disclosure criterion, 7% with the currency criterion, 5.8% with the authorship criterion and 5.8% with the attribution criterion. Only three websites met all JAMA criteria, and these websites belonged to professional organizations. None of the websites had the HONcode logo. Mean FRES and FKGL were 47.6 and 11.6, respectively. CONCLUSIONS: The quality of web-based information about early orthodontic treatment is poor, and readability is insufficient. More accurate and higher quality Internet sources are required on the web.

RESUMO

BACKGROUND: Informed consent as stipulated in regulatory human research guidelines requires volunteers to be well-informed about what will happen to them in a trial. However, researchers may be faced with the challenge of how to ensure that a volunteer agreeing to take part in a clinical trial is truly informed. This study aimed to find out volunteers' comprehension of informed consent and voluntary participation in Human Immunodeficiency Virus (HIV) clinical trials during the registration cohort. METHODS: We conducted a qualitative study among volunteers who were enrolled in the registration cohort of HIV clinical trials in Dar es Salaam, Tanzania. A purposive sampling strategy was used to obtain twenty study participants. The data were collected between June and September 2020 using a semi-structured interview guide. In-depth interviews were used to collect the data to obtain deep insights of the individual study participants on the comprehension of informed consent and participation in the clinical trial. A thematic analysis approach was used to analyze the data. Themes and subthemes were supported by the quotes from the participants. RESULTS: Volunteers described comprehension of informed consent from different perspectives. They reported that various components of the informed consent such as study procedure, confidentiality, risk and benefits were grasped during engagement meetings. Furthermore, the volunteers' decision to participate in the registration cohort was voluntary. However, trial aspects such as health insurance, free condoms, and medical checkups could have indirectly influenced their reluctance to withdraw from the study. CONCLUSION: Engagement meetings may increase the comprehension of informed consent among potential participants for HIV clinical trials. However, trial incentives may influence participation, and thus future research should focus on the challenges of giving incentives in the study. This will ensure comprehension and voluntary participation in the context of HIV clinical trials.

RESUMO

A key question in research on the neurobiology of language is to which extent the language production and comprehension systems share neural infrastructure, but this question has not been addressed in the context of conversation. We utilized a public fMRI dataset where 24 participants engaged in unscripted conversations with a confederate outside the scanner, via an audio-video link. We provide evidence indicating that the two systems share neural infrastructure in the left-lateralized perisylvian language network, but diverge regarding the level of activation in regions within the network. Activity in the left inferior frontal gyrus was stronger in production compared to comprehension, while comprehension showed stronger recruitment of the left anterior middle temporal gyrus and superior temporal sulcus, compared to production. Although our results are reminiscent of the classical Broca-Wernicke model, the anterior (rather than posterior) temporal activation is a notable difference from that model. This is one of the findings that may be a consequence of the conversational setting, another being that conversational production activated what we interpret as higher-level socio-pragmatic processes. In conclusion, we present evidence for partial overlap and functional asymmetry of the neural infrastructure of production and comprehension, in the above-mentioned frontal vs temporal regions during conversation.

RESUMO

BACKGROUND/PURPOSE: Vitiligo is a depigmenting disorder that affects up to 2% of the population. Due to the relatively high prevalence of this disease and its psychological impact on patients, decisions concerning treatment can be difficult. As patients increasingly seek health information online, the caliber of online health information (OHI) becomes crucial in patients' decisions regarding their care. We aimed to assess the quality and readability of OHI regarding phototherapy in the management of vitiligo. METHODS: Similar to previously published studies assessing OHI, we used 5 medical search terms as a proxy for online searches made by patients. Results for each search term were assessed using an enhanced DISCERN analysis, Health On the Net code of conduct (HONcode) accreditation guidelines, and several readability indices. The DISCERN analysis is a validated questionnaire used to assess the quality of OHI, while HONcode accreditation is a marker of site reliability. RESULTS: Of the 500 websites evaluated, 174 were HONcode-accredited (35%). Mean DISCERN scores for all websites were 58.9% and 51.7% for website reliability and treatment sections, respectively. Additionally, 0/130 websites analyzed for readability scored at the NIH-recommended sixth-grade reading level. CONCLUSION: These analyses shed light on the shortcomings of OHI regarding phototherapy treatment for vitiligo, which could exacerbate disparities for patients who are already at higher risk of worse health outcomes.
