Association between Age and Patients’ Perceptions of Safety in Hospitals during the COVID-19 Pandemic: A Cross-sectional Study

AimThis study aimed to explore patients' perceptions of factors contributing to patient safety during hospitalization for COVID-19, with a focus on differences among three distinct adult age groups. MethodsA cross-sectional study was conducted. Data were collected from 533 patients hospitalized with COVID-19 in nine Brazilian university hospitals between April and December 2021. Sociodemographics, health conditions, and the Patient Measure of Safety (PMOS) data were gathered via telephone interviews. Descriptive statistics and ANOVA were used to compare the mean scores across PMOS items, domains, and total scores by age groups (18-44; 45-64; and 65+ years). ResultsPatients aged 45 to 64 years reported the highest perception of safety, while those aged between 18 to 44 years reported the lowest. Statistically significant differences in safety perceptions were observed across age groups. The younger adult group (18-44 years) reported lower overall PMOS scores, particularly in areas such as equipment, access to resources, and organization and care planning, compared to the middle-aged group. Younger adults were more critical of aspects including attentiveness to patient concerns, availability of health professionals, space, and equipment, teamwork skills, and information sharing between the healthcare team and patients. ConclusionPerception of factors contributing to patient safety during the COVID-19 pandemic varied across different age groups. Understanding these differences can inform the development of targeted strategies to incorporate patient perspectives into hospital safety initiatives, indicators development, and research to improve patient safety in hospital settings.

The effects of acute exercise on emotional pattern separation in adolescents and young adults

Acute exercise has been associated with cognitive improvements, particularly in memory processes linked to the hippocampus, such as the ability to discriminate between similar stimuli, called hippocampal pattern separation. This can be assessed behaviorally with a mnemonic discrimination task and neurally with functional magnetic resonance imaging (fMRI). Additionally, previous research has shown an emotional modulatory effect on pattern separation, involving the amygdala. In this randomized between-subject study, we investigated whether a 10-minute bout of moderate-intensity exercise, compared to rest, could enhance pattern separation of neutral and emotional images in a group of healthy adolescents and young adults (n=53). Our results showed no significant effects of exercise on either mnemonic discrimination performance or neural activity in the hippocampus and amygdala. Additionally, arterial spin labeling (ASL) confirmed that there were no significant differences in cerebral blood flow between exercise and rest. We did observe worse discrimination for images with a higher similarity level and worse discrimination for highly similar positive images compared to negative and neutral images. However, there were no significant correlations between behavioral outcomes and neural activity. Exploratory analysis revealed a neural signal consistent with pattern completion in the bilateral CA1 and left CA3, but no evidence of pattern separation. Future studies should optimize the exercise characteristics necessary to robustly enhance pattern separation.

Immersive documentary journalism: exploring the impact of 360° virtual reality compared with a 2D screen display on the responses of people toward undocumented young migrants to Spain

The term ‘MENA’ refers to ‘Menores Extranjeros No Acompañados’ (‘unaccompanied foreign minors’) who are child immigrants to Spain who entered alone without legal documentation. Over the years, ‘mena’ has become a pejorative term associated with criminality, a view especially promoted by some on the political far right. In this article, we describe an experiment where virtual reality (VR) was used to place people among a group of young adults with a ‘MENA’ background (‘ex-mena’) to explore how their experience might alter their attitudes about the plight of the MENA. In particular, we were interested in the different influence of a 360 3D video or the same video on a 2D large screen, both experienced through the same VR head-mounted display. There were 51 people recruited for the experimental study, 28 of whom experienced the video in the screen condition and 23 in the 360 video condition. In addition to questionnaires, a sentiment analysis was carried out on short essays that participants wrote after their experience. The results show that sentiment was greater for the 360 video condition than the screen. Lower sentiment scores are associated with sadness, media bias, feeling bad about the conditions of the MENA, the difficulty of integration, and the utility of understanding and empathy. Higher sentiment scores are associated with empathy due to being closer to the situation, knowing the story of the migrants better, politicization, prejudging, feeling sorry for the manipulation of the migrants, and failure of action by the authorities. The 360 video approach used could be an important tool for documentary journalism.

Comparison Between Ecological Momentary Assessment and Self-Report of Awake Bruxism Behaviours in a Group of Healthy Young Adults.

The aim of this investigation was to compare the self-reported frequency of awake bruxism (AB) behaviours by means of a validated single-observation point questionnaire (i.e., Oral Behaviour Checklist [OBC]) with the frequency reported in real-time with an Ecological Momentary Assessment (EMA) over 1 week. One hundred healthy young adults took part in the study. The frequency of some activities belonging to the spectrum of AB behaviours (i.e., teeth contact, mandible bracing, teeth clenching, teeth grinding) was evaluated using the EMA approach with smartphone technology support over 1 week. The OBC questionnaire was used to evaluate the self-reported frequency of the same AB behaviours. Spearman's rank correlation coefficient was adopted to test the correlation between the average score of each OBC question considered (i.e., teeth contact, mandible bracing, teeth clenching, teeth grinding) and the average frequency of the corresponding EMA item. Statistical analysis showed a weak-to-moderate level of correlation between the two different AB assessment methods. Mandible bracing showed the highest level of correlation, while teeth grinding had the lowest one. While the OBC represents a valid and easy-to-administer screening tool for evaluating bruxism behaviours, the EMA approach provides a more detailed real-time report on AB behaviours.

Comparison of inflammatory mediator cytokine responses to inactivated virus platform COVID-19 vaccines between elderly and young adult populations

The coronavirus disease 2019 (COVID-19) pandemic has encouraged global vaccine research, yet vaccine effectiveness in the elderly remains a concern due to immunosenescence. The aim of this study was to compare the cytokine response elicited by an inactivated virus-based COVID-19 vaccine between elderly and young adults, focusing on key cytokines involved in cellular and humoral immunity: tumor necrosis factor-alpha (TNF-α), interleukin (IL)-2, IL-6, IL-10, and interferon-gamma (IFN-γ). A cross-sectional study was conducted in the Jakarta-Bogor region of Indonesia from January 2023 to December 2023. The study population was divided into two age cohorts: elderly (60−85 years) and younger adults (30−40 years). Blood samples were collected twice, after the first booster dose and four weeks after the second booster dose. Serum cytokine concentrations were measured using Luminex assays with microparticles conjugated to monoclonal antibodies against TNF-α, IL-2, IL-6, IL-10, and IFN-γ. Comparisons of the cytokine levels were conducted using Student’s t-tests or Mann-Whitney U tests as appropriate. A total of 74 individuals were included, with 37 each in the elderly and young adult groups. The results showed significant differences in cytokine responses between the two age groups. After the first booster, the levels of IL-6 and IFN-γ were significantly higher in young adults compared to the elderly. After the second booster, the levels of IL-6 were still significantly higher in the young adult group compared to the elderly group (p=0.001). Data indicated that after the second booster dose, the levels of TNF-α increased significantly in the young adult group only (p=0.004), while the levels of IL-2 (p=0.040) and IFN-γ (p=0.006) increased in the elderly group only compared to after the first dose. IL-10 levels increased in both groups (both had p=0.020). This study highlights that young adults had stronger pro-inflammatory responses, while the elderly relied more on IL-2 and IFN-γ for T-cell immunity, suggesting the need for vaccination strategies for the elderly to optimize immune responses.

A Personalized Data Dashboard to Improve Compliance with Ecological Momentary Assessments in College Students: Protocol for a Microrandomized Trial.

Ecological momentary assessments (EMA) are ideal for capturing the dynamic nature of young adult substance use behavior in daily life and identifying contextual risk factors that signal higher-risk episodes. These methods could provide a signal to trigger real-time intervention delivery. Study compliance and engagement are common barriers to participation but may be improved by personalizing messages. This study compares compliance outcomes between one group of young adults receiving standard (generic) prompts at each assessment and another group that received additional personalization and an updated data dashboard (DD) showing study progress to date at 1 randomly selected prompt per day. The primary objectives are to (1) develop a real-time DD for giving participants personalized updates on their progress in the study and (2) examine its preliminary overall effects on study compliance and experiences. Secondary objectives are to identify person-, day-, and moment-level characteristics associated with study compliance and person-level characteristics associated with perceived usefulness of the DD. This is a protocol for Project ENGAGE, a 2-arm randomized controlled trial. Arm 1 (EMA group) is engaged in a standard EMA protocol, and arm 2 (EMA+DD group) is engaged in the same study but with additional personalization and feedback. Inclusion criteria are (1) previous participation in a recent college student survey about health behavior and mental health who indicated willingness to participate in future research studies and (2) indicated past-month alcohol use; lifetime marijuana, hashish, or Delta-8-tetrahydrocannabinol (THC) use; or some combination of these on that survey. All participants in this study completed a baseline survey; EMA at 11 AM, 2 PM, 5 PM, and 8 PM each day for 21 days; and an exit survey. Participants in arm 2 engaged in a microrandomized trial, receiving a personalized DD at 1 randomly selected prompt per day. Primary outcomes include whether a survey was completed, time to complete a survey, and subjective experiences in the study. Primary analyses will compare groups on overall study compliance and, for arm 2, use marginal models to assess the momentary effect of receiving 1 updated DD per day. Approval was granted by the university's institutional review board on February 8, 2023. Recruitment via direct email occurred on March 30 and April 6, 2023; data collection was completed by April 29, 2023. A total of 91 individuals participated in the study. Results have been accepted for publication in JMIR Formative Research. Results from the evaluation of this study will indicate whether providing (at randomly selected prompts) real-time, personalized feedback on a participant's progress in an EMA study improves study compliance. Overall, this study will inform whether a simple, automated DD presenting study compliance and incentives earned to date may improve young adults' compliance and engagement in intensive longitudinal studies.

A Web-Based Intervention to Support a Growth Mindset and Well-Being in Unemployed Young Adults: Development Study.

Engaging young adults in the labor market is vital for economic growth and well-being. However, the path to employment often presents setbacks that impact motivation and psychological functioning. Research suggests exploring positive psychology interventions in job-seeking and scaling the delivery of these using technology. However, dropout rates are high for self-administered psychological interventions on digital platforms. This challenge needs to be addressed for such platforms to be effective conveyors of psychological interventions. This study addresses this challenge by exploring user-oriented methods and proposes persuasive features for the design and development of a new web-based intervention targeting young unemployed adults. This study aims to provide an overview of a new positive psychology wise intervention, including its theoretical underpinnings and human-centered design methodology, targeting young, unemployed adults. Researchers collaborated with designers, developers, and stakeholders to design a web-based positive psychology intervention that leverages evidence-based wise interventions. Key improvements and adaptations were explored through formative usability testing with 13 unemployed young adults aged between 18 and 25 years (the target population). Qualitative usability testing data were collected, analyzed, and integrated into the ongoing design process as iterative improvements. The result of this study is a modular intervention web application named RØST, designed to align with the user needs and the preferences of the specific end-user group of unemployed young adults. During the project, this application evolved from early concept sketches and prototypes into a developed solution ready for further testing and use. Insights from both end-user feedback and rich user observation gained in the study were used to refine the content and the design. To increase targeted end users' motivation, persuasive design features including praise, rewards, and reminders were added. The web application was designed primarily to be used on mobile phones using text messaging for reminders. The development process included technical and data protection considerations. This study offers valuable insights into developing psychological or behavioral interventions to support unemployed young adults by documenting the design process and the adaptation and combination of diverse theoretical and empirical foundations. Involving stakeholders and end users in the development enabled relatable content development and resolved potential usability problems. An essential implication is the finding that end-user feedback and insights are crucial in shaping interventions. However, we experienced tensions between the evidence-based interventions and the human-centered design approaches. These tensions were not resolved and highlighted a need for ongoing user motivation support through monetary rewards, which were incorporated into the final web app design.

Distribution of Belin-Ambrosio indices using Pentacam HR for normal patients aged 6 to 21 years in the Riyadh area

Objectives: To ascertain the Belin-Ambrosio indices distribution for Saudi patients aged 6-21 years in Riyadh. Method: Participants in this prospective, cross-sectional, observational, multicenter study ranged in age from 6 to 21 years old and were seen in several no n-ophthalmic emergency departments in Riyadh, Saudi Arabia, in 2017. Scheimpflug corneal tomography system in rotation was used to measure the cornea. Following optometric exams, corneal imaging and KC index measurements were performed using the Pentacam Results: The study's 366 participants were examined once the exclusion criteria were applied. All children's mean and standard deviation (SD) age was 17.41±4.83 years (range: 6–21 years). All Belin-Ambrosio indices percentiles for pediatric, adolescence, and young adult groups are within normal ranges. A comparison between Belin-Ambrosio indices and age demonstrates that the age groups have a statistically significant difference following indices topo astig, BAD Db, BAD Dp, BAD Dt, BAD Da, BAD Dy, BAD D, ART Min, ART Max and ART Avg with p-value 0.05. Also, the correlation coefficient results show a statistically significant correlation between Belin-Ambrosio indices and age with the following indices: Topo Astig, BAD Db, BAD Dp, BAD Dt, BAD Da, BAD Dy, BAD D, ART Min, ART Max, and ART Avg with p-value 0.05 as the age increases BAD Dt and BAD Dy, ART Min, ART Max, and ART Avg decrease. Also, As the age increases, the Topo Astig, BAD Db, BAD Dp, BAD Da, and BAD D increase. The correlation coefficient ranges from 0.11 negative weak to 0.65 negative moderate, and from positive 0.13 to negative strong 0.78. Conclusion:The usual range was seen in the Belin-Ambrosio indices. The Belin-Ambrosio indices and age groups differed statistically significantly.

Juvenile Spring Eruption: A Report on an Outbreak and 2 Sporadic Cases in French Military Personnel.

Juvenile spring eruption is a sun-related skin eruption primarily affecting boys or young adult males. The pathophysiology is unknown, but there appears to be a link with sun exposure in cold weather. It can cause small outbreaks, particularly in groups of children or young adults. The primary lesions can be pruritic erythema, with or without associated papules, vesicles, or bullae. They are notable for almost exclusively affecting the ears. Spontaneous healing occurs within a few days without leaving scars. We report an outbreak and 2 sporadic cases that occurred at the Valdahon military camp in France between 2021 and 2024 among military personnel.

The interplay among sleep patterns, social habits, and environmental cues: insights from the Spanish population and implications for aligning daily rhythms.

The interplay among sleep patterns, social habits and environmental cues is becoming increasingly more important for public health and wellbeing due to its connection to circadian desynchronization. This paper explores said connections in Spain (which has an official and solar time mismatch), introducing the "Three Times Score" ‒which is based on questions widely used in the field‒ as a complementary tool for exploring the interplay of daily rhythms. The questionnaire covers sleep-related habits, social time, and environmental time. The study includes 9,947 participants (34.89 ± 12.15 y/o, mean ± SD; 5,561 women) from different Spanish regions. Sleep parameters were obtained for work and free days, as well as a modified version of the sleep-corrected midsleep on free days (MBFbc) and a parameter similar to social jet lag, both derived from bed time rather than sleep time. A number of indexes were computed to compare bed and work-related habits, together with natural light/dark cycle, along with the Three Times Score. Mixed-effect regression analysis was used to test whether the biological, social and environmental factors included in the study significantly predicted the sleep-related parameters: bedtime, wake-up time, time in bed and mid-bedtime. Temporal differences were found between work and free days, with waking-up occurring 2 h earlier on work days (7:10 ± 0:01) than on free days (9:15 ± 0:01). Bed times were 1 h earlier on work days (23:46 ± 0:01) than on free days (00:45 ± 0:01), whereas time in bed was over 1 h shorter on work (7 h 23 min) versus free (8 h 29 min) days. Strong correlations were found between work starting time and waking-up and bedtimes on workdays. Women went to bed earlier and woke up later, spending more time in bed. Differences in sleep habits were observed between work and free days across all age groups. The group of younger adults (18-30) reported going to bed later than older and younger groups, especially on free days. Adolescents and young adults also woke-up later than other age groups, especially on free days. Social jet lag (relative to bed time) and desynchronization indexes also varied with age, with younger adult participants exhibiting higher levels. Seasonal differences were limited, with minor variations between winter and summer. According to the multiple regression analysis, social (day type, work start time, alarm clock usage), biological (age, gender, in most cases related to sex) and environmental (sunset time) factors significantly contribute to predicting sleep/bed related schedules. This study provides insights into sleep habits in the Spanish population, introducing the Three Times Score as a complementary tool for exploring the interactions between sleep/bed-related habits, natural darkness and work-related schedules. Understanding this interplay is crucial for developing tailored interventions to improve sleep and wellbeing.

Exploring the perceptions and experiences of diabetes management and self-regulation in young adults using a continuous glucose monitoring device

Young adults face many pressures as they start being independent and responsible for their own actions and decisions. The use of continuous glucose monitoring has been shown to improve medical outcomes in diabetes management, but the mechanism of these improvements needs further investigation. This study aimed to examine the self-regulatory experiences and behaviours of a group of young adults using continuous glucose monitoring to manage type 1 diabetes. An exploratory qualitative approach was taken, using six virtual semi-structured interviews with young adults living with type 1 diabetes and using continuous glucose monitoring. A thematic analysis was used to identify themes from the gathered data. In this study, three themes demonstrated reciprocal determinism in that the observation of the continuous glucose monitoring results led to changes in the behaviours of the participants. The concepts of feedback and feedforward were also evident in the information provided by continuous glucose monitoring and the adjustment of the participants to achieve their personal blood glucose goals. The results of this study thus support the fact that self-regulation of those living with type 1 diabetes can be improved using continuous glucose monitoring as a tool for observation of blood glucose fluctuations and can, as a result, lead to changes in diabetes management behaviours and health outcomes. Continuous glucose monitoring provides the opportunity to observe the consequences of diabetes management behaviours, which activates the self-regulation processes of feedback and feedforward. This process has the potential to improve diabetes management behaviours in this vulnerable group.

Clinical characteristics and outcomes in middle-aged Fontan patients

BackgroundMiddle-aged Fontan patients are underrepresented in contemporary studies. The purpose of this study was to describe the clinical characteristics and outcomes in middle-aged patients with Fontan palliation. MethodsAll adults with Fontan palliation were divided into ‘middle-aged’ group (>40 years of age at baseline encounter), and ‘young adult’ group. Clinical characteristics were assessed across multiple domains (atrial arrhythmias, heart failure, and hepatorenal function). Clinical outcomes were assessed as composite outcome of death/heart transplant. ResultsOf 455 adults (median age 26 years), 63 (14 %) were middle-aged adults while 392 (86 %) were young adults. Compared to the young adult group, the middle-aged group had a higher prevalence of atrial arrhythmias, greater neurohormonal activation, and worse hepatorenal function. Of 63 patients in the middle-aged group, 26 (41 %) patients died, and 4 (6 %) patients underwent heart transplant. The middle-aged group had a higher 5-year cumulative incidence of death/transplant (45 % versus 21 %, p < 0.001), and 10-year cumulative incidence of death/transplant (64 % versus 29 %, p < 0.001) compared to the young adult group. Higher pulmonary artery wedge pressure (hazard ratio 1.18 [1.09–1.27]), and higher model for end-stage liver disease excluding international normalized ratio score (hazard ratio 1.07, [1.03–1.14]), were associated with death/transplant. ConclusionsAbout 14 % of adults with Fontan palliation were middle-aged, and these patients had higher prevalence of cardiovascular comorbidities, hepatorenal dysfunction, and mortality. These data underscore the need for better risk stratification strategies to identify patients at risk for adverse outcomes and allow for early referral for transplant evaluation in this emerging subpopulation. Clinical summaryThe purpose of this study was to describe the clinical characteristics (comorbidities and end-organ dysfunction) and outcomes (death/transplant) in middle-aged patients with Fontan palliation. Of 455 patients (median age 26 years), 63 (14 %) were middle-aged adults while 392 (86 %) were young adults. Compared to the young adult group, the middle-aged group had a higher prevalence of atrial arrhythmias, greater neurohormonal activation, worse hepatorenal function, and higher risk of death/transplant. The correlates of death/transplant were higher pulmonary artery wedge pressure and hepatorenal dysfunction. These data underscore the need for better risk stratification in this emerging population.

STI Rates Among High-Risk Youth Undeterred During Early COVID-19 In A HIV Care Clinic

Abstract Background In recent years, the United States has observed increasing rates of sexually transmitted infections (STIs). Rates are highest amongst the teen and young adult age groups. In addition to the immense healthcare costs associated with STIs, long-term sequelae can be severe on the individual level. The risk of infertility is particularly high for those with repeated or prolonged infection. Upon entering the COVID-19 pandemic, it was unclear if the widespread behavioral changes and disruptions in routine care practices to minimize the further spread of COVID-19 would cause an increase or decrease in the United States’ STI rates. This study sought to determine if there was a change in the incidence of STIs during the first year of the COVID-19 pandemic compared to the year prior in a population at high risk for STIs. Methods A retrospective chart review was performed for 330 patients aged 12 to 41 years (mean 20.2 years, median 20 years, standard deviation 3.75 years) with human immunodeficiency virus (HIV) or on pre-exposure prophylaxis (PrEP) to prevent the acquisition of HIV, who presented for preventative and acute care appointments at a multidisciplinary pediatric and young adult HIV Clinic in the year prior to and during the first year of the COVID-19 pandemic (March 22, 2019-March 21, 2021). Utilizing telehealth, rapid COVID-19 screening, and multimodal patient communication, increased efforts were made in this clinic during the pandemic to maintain appropriate STI screening, testing, treatment, and rescheduling of routine visits when appropriate to minimize COVID-19 exposure and spread. Comparisons were made between the two time periods, which evaluated the incidences of individual and overall STIs diagnosed per person-years, STIs per total tests performed, and time to treatment initiation. Results Between one year prior to and the first year during the COVID-19 pandemic, this clinic experienced no statistically significant rate changes of sexually transmitted infections. A non-significant decreased incidence of chlamydia (22 cases per 100 person-years and 18 cases per 100 person-years, respectively) and unchanged rates of gonorrhea (22 cases per 100 person-years and 22 cases per 100 person-years, respectively) and syphilis (16 cases per 100 person-years and 15 cases per 100 person-years, respectively) were observed. The median times to treatment remained largely unchanged. Conclusion This HIV care clinic experienced a decreased chlamydia infection rate, a trend similar to the CDC United States STI data during this time period. In contrast to the nationally reported increased rates of gonorrhea and syphilis, this clinic experienced unchanged rates. The lack of change in our cohort could reflect that the benefits of a multidisciplinary HIV care model persist despite a pandemic that disrupted routine medical care and behavior practices.

Forensic Medical Evaluation of Non-Fatal Traumatic Head Bone Fractures

Head bone fractures are encountered in forensic medicine practice due to their origin. In the present study, we aimed to evaluate the demographic data, injury characteristics, clinical findings accompanying bone fractures and forensic reports of cases with skull fractures and to share them with the literature. In this study, cases with non-fatal traumatic skull fractures that did not result in death admitted to our department during the 10-year period between 01.01.2014 and 31.12.2023 were included in the study. Hospital documents and investigation documents of the cases were retrospectively analyzed. It was determined that 75.6% of the cases were male and the mean age was 37±9.6 years. It was determined that 56.2% of the skull fractures occurred as a result of traffic accidents, the most common fracture was the frontal bone (n=206, 53.4%) and 54.1% of the cases were linear fractures. In our study, it was determined that skull fractures were most common in males, in the young adult age group, most commonly due to traffic accidents, and in the form of linear fractures in the frontal bone. The findings were consistent with the literature. When preparing a forensic report on skull fractures, the location of the fracture, the type of fracture and the number of fractures are important in terms of determining the life threat and the effect of the fracture on life functions.

Correlation between sphenoid sinus pneumatization and sella turcica dimensions using computed tomography.

This study was performed to determine the dimensions of the sella turcica (ST) in relation to sex, age groups, and sphenoid sinus (SS) pneumatization patterns in a cohort of Iraqi individuals. This cross-sectional study analyzed computed tomography images of 99 individuals (53 men, 46 women) aged 24 to 59 years to measure ST dimensions, including length, width, height, depth, and surface area. SS pneumatization was classified by sex and age. We also examined the relationship between ST size and SS pneumatization patterns. Women exhibited a significantly greater mean ST depth (9.37 mm) than men (8.19 mm). The ST diameter was significantly larger in the middle-aged group (13.1 mm) than in the young adult group (11.83 mm). The ST area showed a highly significant difference between sexes. The sellar pneumatization pattern was the most common, whereas the conchal pattern had the lowest prevalence. A significant correlation was observed between ST size and SS pneumatization. The ST depth and diameter showed statistically significant differences across sex and age groups, respectively. The variability in SS pneumatization patterns underscores the importance of considering pneumatization types during surgical planning to minimize the risk of iatrogenic injury and improve treatment outcomes.

Effects of Time Intervals and Semantic Weight on Action Fluency Tasks in Older Adults

Objectives: The purpose of this study was to investigate the differences in performance of action fluency tasks (AFT) based on time intervals and the semantic weight of verbs among groups of healthy young and older adults and to explore the correlation between working memory and the performance. Methods: A total of 62 Korean-speaking individuals, consisting of 31 healthy young and older adults, participated in the AFT and their performance was analyzed by the semantic weight of verbs (Heavy vs. Light) and time interval (first 30 sec vs. last 30 sec). They also participated in a working memory task. To measure working memory capacity, word span tasks (WST) - forward and backward were conducted. Results: In both groups, performance on the AFT was higher in the first 30 sec and there were more productions of heavy verbs compared to light verbs. Additionally, a positive correlation was observed in the older adults between the number of heavy verbs produced in both the first 30 sec and last 30 sec and the scores on the WST-backward. Conclusion: In this study, through a qualitative analysis based on time intervals and semantic weight, we confirmed that the first 30 sec of the AFT can be a useful source for analyzing results. Furthermore, it highlighted that the semantic weight of verbs could serve as an efficient method for predicting aging.

Outcome of adolescents and young adult acute myeloid leukemia patients compared with middle-aged patients: A single centre retrospective experience

Adult acute myeloid leukemia (AML) patients under the age of 60 often receive similar intensive treatments, while outcomes between the adolescent and young adult (AYA) age group (18−39) and middle-aged adults (40–60 years) were seldom reported. We aim to study the characteristics and outcomes of AYA patients in comparison to middle-aged adults. A retrospective analysis was performed on AYA patients treated at Princess Margaret Cancer Center between 2008 and 2018. The primary outcomes include overall survival (OS), cumulative incidence of relapse (CIR), and non-relapse mortality (NRM).A total of 174 AYA patients and 176 middle-aged patients were included, with propensity score matching adjusting for potential major confounders. Comparing AYA and middle-aged patients, 5-year OS rates were similar at 54.6 % vs. 56.5 % (p=0.91), CIR rates at 29.5 % vs. 23.1 % (p=0.31), and similar NRM rates. Notably, non-transplanted AYA patients had a significantly higher CIR (39.8 %) compared to middle-aged patients (19.6 %) (p=0.0324), with more primary refractory/early relapsing disease. An observed trend toward improved OS in AYA patients post-2015 coincided with FLAG-IDA and haploidentical transplant implementations.In conclusion, the study suggests that AYA patients, particularly those not undergoing transplantation, may benefit from more intensive treatment strategies, emphasizing the need for tailored approaches in this age group.

Research on Universal Design of Smart Home Interface Navigation Based on Visual Interaction

The study focuses on analyzing the design characteristics of display and control interface navigation in smart home terminals for users of different ages. By examining the design features of the current typical smart home terminal display and control interface navigation, interface navigation design is the research object. Experimental research is conducted with young adult group (n = 15) and middle-aged to elderly group (n = 15) participants to identify the optimal interface navigation design through specific behavioral indicators, eye movement indicators, and subjective indicators. The results show that different interface layouts impact task completion performance. Middle-aged and older individuals perform better with multi-level highlighting operations. Both age groups prefer interface layouts featuring less-level dual navigation, specifically the left-side type, and multi-level highlighting. These results can improve the versatility of smart home interface design, expand the user base, and provide information for developing smart products.

The influence of positivity and self-efficacy beliefs on family functioning among young adults in Italy and Colombia.

Research suggests that positivity and self-efficacy beliefs may impact adaptive behavior and developmental outcomes, such as social adjustment and subjective wellbeing. The present study explored the effect of positive dimensions (positivity and self-efficacy beliefs) and individual characteristics (gender, type of country, age, and sexual orientation) on family cohesion and flexibility in a group of Colombian and Italian young adults. An online survey was administered to 949 Colombian and 2,073 Italian people aged between 18 and 40 years (M age = 24.3; SDage = 4.5; 67% women). A mediational model was performed to test the influence of positivity on family functioning via the mediational role of self-efficacy beliefs, analyzing the moderated effects of gender, type of country, sexual orientation, and age. Filial self-efficacy mediated the effect of positivity on family functioning, showing stronger paths in men and Colombian participants than in women and Italian counterparts. Regulatory self-efficacy mediated the associations between positivity and family functioning for both genders and types of countries. The results suggest that positivity and self-efficacy beliefs may allow families to engage in more adaptive family functioning across countries and genders. Further research should focus on implications from a cross-national perspective to examine other culture-specific factors that may impact family adjustment.

Relative muscle indices and healthy reference values for sarcopenia assessment using T10 through L5 computed tomography skeletal muscle area

Sarcopenia is the age-related loss of skeletal muscle mass and function. Computed tomography (CT) assessments of sarcopenia utilize measurements of skeletal muscle cross-sectional area (SMA), radiation attenuation (SMRA), and intramuscular adipose tissue (IMAT). Unadjusted SMA is strongly correlated with both height and body mass index (BMI); therefore, SMA must be adjusted for body size to assess sarcopenic low muscle mass fairly in individuals of different heights and BMI. SMA/height (rather than SMA/height2\\documentclass[12pt]{minimal} \\usepackage{amsmath} \\usepackage{wasysym} \\usepackage{amsfonts} \\usepackage{amssymb} \\usepackage{amsbsy} \\usepackage{mathrsfs} \\usepackage{upgreek} \\setlength{\\oddsidemargin}{-69pt} \\begin{document}$$SMA/height^2$$\\end{document}) provides optimal height adjustment, and vertebra-specific relative muscle index (RMI) equations optimally adjust for both height and BMI. Since L3 measurement is not available in all CT scans, sarcopenic low muscle mass may be assessed using other levels. Both a mid-vertebral slice and an inferior slice have been used to define ‘L3 SMA’, but the effect of vertebral slice location on SMA measurements is unexplored. Healthy reference values for skeletal muscle measures at mid- and inferior vertebra slices between T10 and L5, have not yet been reported. We extracted T10 through L5 SMA, SMRA, and IMAT at a mid-vertebral and inferior slice using non-contrast-enhanced CT scans from healthy, adult kidney donor candidates between age 18 and 73. We compared paired differences in SMA between the mid-vertebral slice versus the inferior slice. We calculated the skeletal muscle gauge as SMGHT=SMRA∗SMIHT\\documentclass[12pt]{minimal} \\usepackage{amsmath} \\usepackage{wasysym} \\usepackage{amsfonts} \\usepackage{amssymb} \\usepackage{amsbsy} \\usepackage{mathrsfs} \\usepackage{upgreek} \\setlength{\\oddsidemargin}{-69pt} \\begin{document}$$SMG_{HT}=SMRA*SMI_{HT}$$\\end{document}. We used allometric analysis to find the optimal height scaling power for SMA. To enable comparisons with other published reference cohorts, we computed two height-adjusted measures; SMIHT=SMA/height\\documentclass[12pt]{minimal} \\usepackage{amsmath} \\usepackage{wasysym} \\usepackage{amsfonts} \\usepackage{amssymb} \\usepackage{amsbsy} \\usepackage{mathrsfs} \\usepackage{upgreek} \\setlength{\\oddsidemargin}{-69pt} \\begin{document}$$SMI_{HT}=SMA/height$$\\end{document} (optimal) and SMIHT2=SMA/height2\\documentclass[12pt]{minimal} \\usepackage{amsmath} \\usepackage{wasysym} \\usepackage{amsfonts} \\usepackage{amssymb} \\usepackage{amsbsy} \\usepackage{mathrsfs} \\usepackage{upgreek} \\setlength{\\oddsidemargin}{-69pt} \\begin{document}$$SMI_{HT2}=SMA/height^2$$\\end{document} (traditional). Using the young, healthy reference cohort, we utilized multiple linear regression to calculate relative muscle index z-scores (RMIHT\\documentclass[12pt]{minimal} \\usepackage{amsmath} \\usepackage{wasysym} \\usepackage{amsfonts} \\usepackage{amssymb} \\usepackage{amsbsy} \\usepackage{mathrsfs} \\usepackage{upgreek} \\setlength{\\oddsidemargin}{-69pt} \\begin{document}$$RMI_{HT}$$\\end{document}, RMIHT2\\documentclass[12pt]{minimal} \\usepackage{amsmath} \\usepackage{wasysym} \\usepackage{amsfonts} \\usepackage{amssymb} \\usepackage{amsbsy} \\usepackage{mathrsfs} \\usepackage{upgreek} \\setlength{\\oddsidemargin}{-69pt} \\begin{document}$$RMI_{HT2}$$\\end{document}), which adjust for both height and BMI, at each vertebra level. We assessed Pearson correlations of each muscle area measure versus age, height, weight, and BMI separately by sex and vertebra number. We assessed the differences in means between age 18–40 versus 20–40 as the healthy, young adult reference group. We reported means, standard deviations, and sarcopenia cutpoints (mean-2SD and 5th percentile) by sex and age group for all measures. Sex-specific allometric analysis showed that height to the power of one was the optimal adjustment for SMA in both men and women at all vertebra levels. Differences between mid-vertebra and inferior slice SMA were statistically significant at each vertebra level, except for T10 in men.

There were no significant differences in SMA between 18–40 versus 20–40 age groups. Healthy reference values and sarcopenic cutpoints are reported stratified by sex, vertebra level, and age group for each measure.

Measurement of SMA at a mid-vertebral slice is significantly different from measurement of SMA at an inferior aspect slice. Reference values should be used for the appropriate slice. We report sarcopenic healthy reference values for skeletal muscle measures at the mid-vertebral and inferior aspect slice for T10 through L5 vertebra levels. Relative muscle index (RMI) equations developed here minimize correlation with both height and BMI, producing unbiased assessments of relative muscle mass across the full range of body sizes. We recommend the use of these RMI equations in other cohorts.
