Semantic details in autobiographical memory narratives increase with age among younger adults

ABSTRACT It is well documented that older adults, compared to younger adults, produce fewer episodic details and more semantic details when recalling autobiographical memories. However, group comparisons have provided limited insight into the trajectories of detail generation across the lifespan. Utilising an open source dataset [Clark, I. A., & Maguire, E. A. (2023). Release of cognitive and multimodal MRI data including real-world tasks and hippocampal subfield segmentations. Scientific Data, 10(1), 1–29. https://doi.org/10.1038/s41597-022-01899-x], we examined how episodic and semantic detail generation varied with age among 194 younger adults, ages 20-41. We tested whether age differences were mediated by hippocampal subfield volumes and MTL resting-state functional connectivity. Results indicated that semantic details increased with age, while episodic details remained stable. We observed age differences in hippocampal subfield volumes and MTL connectivity, but these measures did not mediate age effects on semantic detail. Based on these and prior findings [Matijevic, S., Andrews-Hanna, J. R., Wank, A. A., Ryan, L., & Grilli, M. D. (2022). Individual differences in the relationship between episodic detail generation and resting state functional connectivity vary with age. Neuropsychologia, 166, 108138. https://doi.org/10.1016/j.neuropsychologia.2021.108138], we suggest a model of diverging episodic and semantic detail generation trajectories across the adult lifespan.

Back to Normal? Harnessing Long Short-term Memory Network to Examine the Associations Between Adolescent Social Interactions and Depressive Symptoms During Different Stages of COVID-19.

Adolescence is a developmental period in which social interactions are critical for mental health. While the onset of COVID-19 significantly disrupted adolescents' social environments and mental health, it remains unclear how adolescents have adapted to later stages of the pandemic. We harnessed a machine learning architecture of Long Short-Term Memory recurrent networks (LSTM) with gradient-based feature importance, to model the association among daily social interactions and depressive symptoms during three stages of the pandemic. A year before COVID-19, 148 adolescents reported social interactions and depressive symptoms, every day for 21days. One hundred sixteen of these youths completed a 28-day diary after schools closed due to COVID-19. Seventy-nine of these youths and additional 116 new participants completed a 28-day diary approximately a year into the pandemic. Our results show that LSTM successfully predicted depressive symptoms from at least a week of social interactions for all three waves (r2 > .70). Our study shows the utility of using an analytic approach that can identify temporal and nonlinear pathways through which social interactions may confer risk for depression. Our unique analysis of the importance of input features enabled us to interpret the association between social interactions and depressive symptoms. Collectively, we observed a return to pre-pandemic patterns a year into the pandemic, with reduced gender and age differences during the pandemic closures. This pattern suggests that the system of social influences in adolescence was affected by COVID-19, and that this effect was attenuated in more chronic stages of the pandemic.

Time trends in stroke risk management among high-risk patients with non-valvular atrial fibrillation in Australia between 2011–2019

BackgroundAtrial fibrillation (AF) is associated with stroke. Major changes to AF management recommendations in 2016–2018 advised that: 1. Stroke risk be estimated using the CHA2DS2-VA score; 2. Antiplatelet agents (APAs) do not effectively mitigate stroke risk; 3. Anticoagulation is prioritised above bleeding risk among high-risk patients; and 4. Non-vitamin K oral anticoagulants (NOACs) are used as first-line anticoagulants. AimTo examine trends in stroke risk management among high-risk patients with non-valvular AF in Australia between 2011–2019. MethodDe-identified data of patients were obtained from 164 separate general practices. Data included information on patient demographics, diagnoses, health risk factors and recent prescriptions. Patients with a diagnosis of non-valvular AF were identified and stroke risk was calculated by CHA2DS2-VA score. High risk patients (i.e. CHA2DS2-VA ≥ 2) were categorised as being managed by oral anticoagulants (OACs, i.e., warfarin or NOACs), APAs only, or neither (i.e., no OACs or APAs) and time trends in prescribing were examined. Multivariate analyses examined the characteristics of patients receiving the guideline recommended OAC management. ResultsData were available for 337,964 patients; 8696 (2.6 %) had AF. Most patients with AF (85.8 %, n = 7116) had high stroke risk. The proportion of high-risk patients managed on OACs increased from 56.7 % in 2011 to 73.7 % in 2019, while the proportion prescribed APAs declined from 31.1 % to 14.0 %. Those receiving neither treatment remained steady (around 12 %). Overall, 26.3 % of patients were inadequately anticoagulated at the end of the study period. There were no age or gender differences in receiving the guideline-recommended therapy, and patients with comorbidities associated with increased stroke risk were more likely to receive OAC therapy. ConclusionsStroke risk management among patients with AF has improved between 2011–2019, however there is still scope for further gains as many high-risk patients remain inadequately anticoagulated. Better stroke risk assessment by clinicians coupled with addressing practitioner concerns about bleeding risk may improve management of high-risk patients.

Exploring age-related differences in metacognitive self-regulation: the influence of motivational factors in secondary school students.

Metacognitive self-regulation is a crucial factor that promotes students' learning and achievement. However, the evidence regarding age differences in metacognitive skills is rather mixed, with some evidence pointing toward further refinement and development and other evidence suggesting declining levels. Academic motivation, an important antecedent of metacognitive self-regulation, has also been reported to decline steeply in adolescence. Hence, this raises the question whether there are any age-related differences in academic motivation and metacognitive self-regulation of adolescents and whether age differences in academic motivation drive decreases in metacognitive self-regulation. A large sample size of 1,027 Greek adolescents (ages 12-16, M age = 13.95, SD = 0.78) was utilized in the present study. Multigroup measurement invariance analyses were deployed to compare the latent means of motivational factors (self-efficacy, task value, mastery, and performance goals) and metacognitive self-regulation across age groups. Cholesky decomposition was applied to test the independent contribution of motivational factors to and the indirect effects of age on metacognitive self-regulation. Invariance analyses revealed scalar invariance for metacognitive self-regulation, language self-efficacy, mastery and performance goal orientations and partially scalar invariance for task value. Older adolescents scored lower on metacognitive self-regulation, mastery and performance goals, and self-efficacy. Older students scored lower on metacognitive self-regulation via indirect effects through Cholesky decomposed motivational factors. Self-efficacy, mastery and performance goals, and task value are similarly understood across adolescents in different age groups. Decreased mastery and performance goals and task value can lead to reduced metacognitive self-regulation in adolescents. The implications of the findings underscore the key role of making students more engaged with lessons' content in order to promote greater academic motivation and prevent decreases in metacognitive self-regulation.

Physical Heart Failure Symptom Clusters Predictive of Delay in Seeking Treatment.

Recent research has focused on the relationship between heart failure (HF) symptom clusters and outcomes, including mortality, hospitalization, functional status, and quality of life. No known studies to date have explored the role of physical HF symptom clusters and delays in seeking treatment. Describe physical symptom clusters in a population of HF patients and determine if a specific cluster is predictive of delay in seeking treatment for HF symptoms. We analyzed combined data from two studies (n = 406) collected during acute HF hospitalization. The Heart Failure Somatic Awareness Scale quantified physical HF symptoms. Delay, measured in days, was collected from the medical record and confirmed by interview. Hierarchical agglomerative clustering techniques determined physical HF symptom clusters. Hierarchical multiple regression analysis was computed to explore predictors of delay. Participants were primarily White, male sex older adults. Three physical HF symptom clusters were identified: discordant, edema-related symptoms, and dyspnea-related symptoms. Hierarchical multiple regression analysis revealed in Step 1 that age was a significant predictor of delay. Our findings provide valuable insight into the role of physical symptom clusters on delay in persons with HF. Through agglomerative hierarchical clustering techniques, we found three physical HF symptom clusters that were then used to determine differences in cluster membership by demographic and clinical variables. Significant age differences were noted by cluster membership with youngest older adults in a discordant symptom cluster.

Validation of the Japanese Version of the Modest Behavior Scale for Adults and Age and Gender Differences

AbstractSocial pressures, such as cultural norms of modesty, are thought to contribute to low self‐esteem in East Asians, and modesty is a key concept in understanding the feelings, thoughts, and social behaviors of this population. Modesty has been found to encompass three aspects: avoidance of attention‐seeking (AA), self‐effacement (SE), and other‐enhancement (OE). The current study validated the Modest Behavior Scale and examined age and gender differences in the three aspects of modesty in a sample of adults aged 20–69 years. A total of 400 Japanese individuals participated in the online survey. The results of hierarchical multiple regression analyses and simple slopes analyses revealed that older people tend not to seek attention but also not to devalue themselves, whereas younger people tend to devalue themselves but not to refrain from seeking attention. This implies that people in different age groups use different modesty strategies. In addition, gender differences were found in AA and OE. The age and gender differences in modesty were discussed in terms of hierarchical relationships and social role expectations.

Unveiling the Shadows: An Exploratory Analysis of Perceived Disadvantages in Intimate Relationships

AbstractIntimate relationships are not characterized only by advantages as they have also a darker side. Accordingly, the current research aimed to identify the disadvantages of being in an intimate relationship in the Greek cultural context. More specifically, Study 1 employed qualitative research methods with a sample of 202 Greek-speaking participants, identifying 94 possible disadvantages. Study 2 employed quantitative research methods with a sample of 525 Greek-speaking participants and classified these disadvantages into 11 broader factors or major disadvantages and three broader domains or primary disadvantages. Participants indicated "Conflicts" as the most important primary disadvantage, followed by the "Emotional burden" and the "Compromises" primary disadvantages. Furthermore, we found that women indicated abusive behaviors, economic dependency, and less freedom factors as more important major disadvantages than men. Additionally, older participants reported making compromises as a more important major disadvantage than younger participants. Moreover, single participants rated several major disadvantages as more important than participants in an intimate relationship. Overall, our study sheds light on the less favorable aspects of intimate relationships and highlights important sex, age, and relationship status differences in perceiving these disadvantages.

Role of Motivation in the Progression of Problem Gambling: A Comparison of Early and Late Adults.

Motivation plays a dominant role in gambling progression. Most studies using motivational scales have revealed that certain motivations are associated with problem gambling. However, age differences were found to be negligible in gambling motivation. This study aimed to examine the role of motivation associated with age differences in problem gambling in Japan. A total of 160 participants over 20 years of age who had gambled within the past six months were randomly recruited from web monitors. In this study, the Japanese version of the modified Gambling Motivation Scale (J-MGMS) was used which comprises six systematic factors: intellectual challenge, excitement, socialization (coping and sociability), social recognition, monetary gain, and amotivation. The Japanese version of the South Oaks Gambling Screening (J-SOGS) was used to assess participants' gambling-related problems. Demographic data, such as gambling frequency, were solicited. Using linear regression analysis, amotivation in all participants, social recognition in early adults (under 30), and amotivation in late adults (30 or over) were associated with J-SOGS scores (adjusted R2 = 0.170, 0.290, 0.156). Among late adults, social recognition was nearly significant, although negative (p = 0.0503). 1) Self-determinant (autonomous) motivations such as excitement and socialization do not contribute to the progression of problem gambling. 2) Two non-self-determinant (non-autonomous) motivations, social recognition in early adults and amotivation in late adults, are predictors of problem gambling. 3) Social recognition is a dichotomic and paradoxical motivation in the progress of problem gambling according to age.

International study on prevalence of itch: examining the role of itch as a major global public health problem.

Very few studies have evaluated the global prevalence of pruritus. To assess its prevalence according to age, sex, ethnicity and geographic region. An international cross-sectional study was conducted in 20 countries from January to April 2023. Participants were asked to complete a questionnaire on sociodemographics, and to confirm the presence or absence of a skin disease in the last 12 months and the presence or absence of pruritus in the last 7 days. The studied sample included 50 552 individuals. The worldwide prevalence of pruritus was 39.8%. The age group ≥ 65 years had the highest prevalence (43.3%). The prevalence was 40.7% among women and 38.9% among men (P < 0.001). There was no significant difference between ethnicities (P = 0.14). Compared with North America (41.2%), the prevalence of pruritus was significantly lower in Europe (35.9%, P < 0.001), Australia (38.4%, P = 0.017), East Asia (40.2%, P = 0.04) and Latin America (36.5%, P < 0.001), and higher in Africa (45.7%, P = 0.007). No significant difference was found with the Middle East (40.2%, P = 0.36). The prevalence of pruritus in BRICS countries (40.3%) was significantly higher than that in developed countries (38.7%) (P < 10-3). Out analysis is limited because there is no information about the severity or type (acute, chronic) of pruritus. The global prevalence of pruritus revealed age, sex and geographic region differences, with no ethnic differences.

Knowledge, attitudes, and perceived Ethics regarding the use of ChatGPT among generation Z university students

Artificial intelligence (AI) has been integrated into higher education (HE), offering numerous benefits and transforming teaching and learning. Since its launch, ChatGPT has become the most popular learning model among Generation Z college students in HE. This study aimed to assess the knowledge, concerns, attitudes, and ethics of using ChatGPT among Generation Z college students in HE in Peru. An online survey was administered to 201 HE students with prior experience using the ChatGPT for academic activities. Two of the six proposed hypotheses were confirmed: Perceived Ethics (B = 0.856) and Student Concerns (B = 0.802). The findings suggest that HE students’ knowledge and positive attitudes toward ChatGPT do not guarantee its effective adoption and use. It is important to investigate how attitudes of optimism, skepticism, or apathy toward AI develop and how these attitudes influence the intention to use technologies such as the ChatGPT in HE settings. The dependence on ChatGPT raises ethical concerns that must be addressed with responsible use programs in HE. No sex or age differences were found in the relationship between the use of ChatGPTs and perceived ethics among HE students. However, further studies with diverse HE samples are needed to determine this relationship. To promote the ethical use of the ChatGPT in HE, institutions must develop comprehensive training programs, guidelines, and policies that address issues such as academic integrity, privacy, and misinformation. These initiatives should aim to educate students and university teachers on the responsible use of ChatGPT and other AI-based tools, fostering a culture of ethical adoption of AI to leverage its benefits and mitigate its potential risks, such as a lack of academic integrity.

Effects of adolescent alcohol exposure on oligodendrocyte lineage cells and myelination in mice: Age and subregion differences

Adolescence is an important phase for the structural and functional development of the brain. The immaturity of adolescent brain development is associated with high susceptibility to exogenous disturbances, including alcohol. In this study, the acquisition of conditioned place preference (CPP) in adolescent mice by alcohol (2 g/kg) and the parvalbumin-positive interneurons (PV+ interneurons), oligodendrocyte lineage cells (OPCs), and myelination in the medial prefrontal cortex (mPFC) were assessed. We aim to determine the age- and subregional-specificity of the effects of alcohol. Alcohol (2 g/kg) was injected intraperitoneally on even days, and saline was injected intraperitoneally on odd days. The control group received a continuous intraperitoneal injection with saline. Differences in alcohol-induced CPP acquisition were assessed, followed by immunohistochemical staining. The results showed a pronounced CPP acquisition in 4- and 5-week-old mice. In the mPFC, there were reduced PV+ interneurons and OPCs in 3-week-old mice and reduced oligodendrocyte numbers in 4-week-old mice. The 5-week-old mice showed impaired myelination and a decrease in the number of PV+ interneurons, mature oligodendrocytes, and OPCs in the mPFC. Since the alterations in 5-week-old mice are more pronounced, we further explored the mPFC-associated subregional-specificity. In the alcohol-exposed mice, the oligodendrocyte numbers were decreased in the anterior cingulate cortex (ACC), PV+ interneuron numbers were declined in the prelimbic cortex (PL), and the number of oligodendrocytes, PV+ interneurons, and OPCs was also decreased with impaired myelination in the infralimbic cortex (IL). Our data suggest that adolescent alcohol exposure notably affected the acquisition of CPP, myelin formation, and the counts of PV+ interneurons, mature oligodendrocytes, and OPCs in the mPFC in 5-week-old mice. Also, the IL subregion was the worst-affected subregion of the mPFC in alcohol-exposed 5-week-old mice. It reveals that the effects of alcohol on adolescence and its mPFC myelination show obvious age- and subregional-specificity.

Employing a Toxic Aging Coin approach to assess hexavalent chromium (Cr[VI])-induced neurotoxic effects on behavior: Heads for age differences

We are facing a rapidly growing geriatric population (65+) that will live for multiple decades and are challenged with environmental pollution far exceeding that of previous generations. Consequently, we currently have a poor understanding of how environmental pollution will impact geriatric health distinctly from younger populations. Few toxicology studies have considered age differences with geriatric individuals. Critically, all top ten most prevalent age-related diseases are linked to metal exposures. Hexavalent chromium [Cr(VI)] is a metal of major environmental health concern that can induce aging phenotypes and neurotoxicity. However, there are many knowledge gaps for Cr(VI) neurotoxicity, including how Cr(VI) impacts behavior. To address this, we exposed male rats across three ages (3-, 7-, and 18-months old) to Cr(VI) in drinking water (0, 0.05, 0.1 mg/L) for 90 days. These levels reflect the maximum contaminant levels determined by the World Health Organization (WHO) and the U.S. Environmental Protection Agency (US EPA). Here, we report how these Cr(VI) drinking water levels impacted rat behaviors using a battery of behavior tests, including grip strength, open field assay, elevated plus maze, Y-maze, and 3-chamber assay. We observed adult rats were the most affected age group and memory assays (spatial and social) exhibited the most significant effects. Critically, the significant effects were surprising as rats should be particularly resistant to these Cr(VI) drinking water levels due to the adjustments applied in risk assessment from rodent studies to human safety, and because rats endogenously synthesize vitamin C in their livers (vitamin C is a primary reducer of Cr[VI] to Cr[III]). Our results emphasize the need to broaden the scope of toxicology research to consider multiple life stages and suggest the current regulations for Cr(VI) in drinking water need to be revisited.

What Motivates Men to Improve Their Health? Understanding the Roles of Self-Esteem and Influential Others in Behaviour Change.

The aim of this study was to examine men's body image confidence, social reflectivity, body image perceptions and external information sources influence regarding body assessments. Data were collected via a cross-sectional survey and found that men have a low motivation toward physical health behaviour changes such as food, alcohol and exercise evaluation, and have generally positive views of their bodies overall. Relationship status, rather than age, defined behavioural and attitudinal differences within the men studied here. Men in this study were largely uninfluenced by celebrities or fashion in developing their own body image perceptions; single males were more likely to turn to friends, the female population generally and societal norms when evaluating themselves. Males in relationships however, weighted their partner's opinion as the greatest influence, followed by their involvement in sport. This study offers an insight into the role of body confidence in male perspectives of the self, which is important for its intrinsic connection to motivations for health behaviours such as body weight management. This has implications for increasing the effectiveness of health-related product and service messaging, and public health messages regarding body weight management for men.

Gender and Age Differences in the Evaluation and Clinical Outcomes of Patients with Palpitations.

Palpitations represent a common clinic complaint. To explore gender and age differences in the evaluation and outcomes of patients with palpitations in outpatient settings. This is a retrospective observational study of 58,543 patients with no known structural cardiac disease or arrythmias presenting to primary care and cardiology clinics in an integrated health system in California with palpitations between January 2017 and December 2021. The primary and secondary endpoints were hospitalization for arrhythmia and all-cause mortality at 1year. Multivariable logistic regression models evaluated the association between gender, age, and outcomes. Men and women were equally as likely to be started on beta-blockers (adjusted OR 0.96, 95% CI 0.90-1.02) and evaluated with electrocardiograms (adjusted OR 0.95, 95% CI 0.90-1.01) and cardiac monitors (adjusted OR 1.04, 95% CI 0.99-1.08). Patients who completed Holter or event monitors had a lower rate of hospitalization for cardiovascular disease at 1year than those without (2.3% vs. 2.7%, p = 0.001). At 1year, women had a lower risk of all-cause mortality (adjusted OR 0.47, 95% CI 0.35-0.64) and hospitalization for atrial fibrillation (adjusted OR 0.47, 95% CI 0.30-0.72) and arrhythmias (adjusted OR 0.73, 95% CI 0.58-0.91) compared to men. Among older women and men (≥ 80years), there was no significant difference in 1-year all-cause mortality (adjusted OR 0.57, 95% CI 0.29-1.12), hospitalization for atrial fibrillation (adjusted OR 0.58, 95% CI 0.17-1.97), or arrhythmias (adjusted OR 1.15, 95% CI 0.12-11.07). There were no gender differences in referrals for cardiac monitoring or prescriptions for beta-blockers. Women had a better prognosis with a lower risk of hospitalization for arrhythmias and death at 1 year compared to men. However, 1-year risks for mortality and hospitalization for arrythmias among older women were comparable to those of older men, underscoring the importance of considering age and gender in managing patients with palpitations.

(118) ORGASM AND HEART RATE VARIABILITY IN FEMALE BREAST CANCER SURVIVORS: RESULTS FROM A PSYCHOPHYSIOLOGY STUDY

Abstract Introduction Over 70 % of female breast cancer survivors suffer from sexual dysfunction. Sexual dysfunction can cause great amounts of stress and negatively impact overall health and well-being. Most studies focus on sexual arousal disorders and hypoactive sexual desire disorders. The research on orgasm in this specific group is limited. A better understanding of sexual function in breast cancer patients may yield potential targets for new treatment strategies for sexual dysfunction in this population. Low heart rate variability (HRV) has been shown to be predictive of erectile dysfunction and female sexual arousal as well as orgasm frequency. Reduced HRV and low cardiac vagal tone have previously been reported in breast cancer survivors during the first year post-treatment. If HRV is a reliable indicator of female sexual dysfunction, it could be used to assess and monitor it in a clinical setting. Objectives This study aimed to explore whether there is a link between HRV and both, sexual arousal and the ability to orgasm. We were expecting to find a difference in HRV between breast cancer survivors and healthy controls as well as orgasmic and anorgasmic women. Methods Participants were prescreened during a telephone interview. We included 40 premenopausal breast cancer survivors currently on hormonal treatment with an age range of 29 to 57 years (M = 43.5, SD = 6.4) and 20 healthy controls with an age range of 22 to 35 (M = 27.6, SD = 3.2). The vaginal pulse amplitude, heart rate variability (SDNN), subjective sexual arousal and self-reported number of orgasms were assessed in response to audiovisual sexual stimuli and vibrotactile clitoral stimulation in breast cancer survivors and healthy controls. Validated patient-reported outcome measures were used to assess sexual dysfunctions (Female Sexual Function Index, Female Sexual Distress Scale − Desire/Arousal/Orgasm), sexual self-esteem (Sexual Self-Esteem Inventory-Short Form), health-related quality of life (Patient-Reported Outcomes Measurement Information System 29 (PROMIS-29) profile questionnaire). Results Breast cancer survivors showed lower sexual function, health-related quality of life, sexual self-esteem and higher sexual distress than healthy controls. Preliminary results show a difference in baseline HRV scores between healthy controls and breast cancer survivors. However, this finding is likely due to age differences between our two groups and not cancer treatment effects. We could find no apparent differences in baseline HRV between anorgasmic and orgasmic women. Further analyses on the predictive value of HRV during sexual arousal for orgasm occurrence will be conducted. Conclusions Our data did not corroborate either of our hypotheses related to baseline HRV. For the evaluation of HRV as a predictor for orgasm occurrence, further exploratory analyses will follow. More research on the physiological parameters of sexual dysfunction is needed to reveal underlying mechanisms and find targets for future therapies.

Age differences in the principal temporo-spatial components of EEG activity during a proactive interference task

Proactive interference (PI) is the disruptive effect of no longer relevant information on current working memory (WM) processing. PI effects in EEG data have been previously found to be altered in healthy aging, although it remains unclear the extent to which such changes reflect delayed or different brain mechanisms employed to overcome PI. Hence, we had twenty-six young (18–34 years) and sixteen old (53–68 years) healthy adults complete a Recent Probes task while EEG was recorded. Compared to young adults, old adults were slower, less accurate and less able to discriminate when they last saw a given stimulus, but PI effects on reaction time were greater in the former, likely due to a general difficulty that old adults had in the task. Temporo-spatial principal component analysis of the EEG data showed young and older adults to differ in terms of temporal and spatial characteristics of brain activity associated with resolving PI. YA showed a factor indicative of a medial frontal negativity (MFN) that showed greater amplitude in low compared to high PI trials. OA, in contrast, showed a late positive component (LPC), although similarly with larger amplitude in low compared to high PI trials. The modulation of the MFN component in YA may reflect the recruitment of cognitive control to overcome PI. The modulation of the LPC in OA may represent the detection of conflict between familiarity and context recollection during PI.

Tantangan Manejemen Pelatihan dalam Mengatasi Perbedaan Usia dan Ketersediaan Waktu di Kursus Pelatihan Komputer Alberto

Research conducted at LKP ALBERTO found problems or challenges that included time and differences between the students, considering that the students had their own responsibilities. Starting from minors who are still attending formal school, or adults who are already working. Plus, the age difference creates different ways of thinking and understanding. The purpose of this research is to find out the challenges and how Alberto's LKP overcomes challenges so that we can propose suggestions or solutions for the LKP. The method used in this research is an interview method where we get direct views from the LKP on student instructors. The interview results show that effective time management is very important to achieve learning goals, but age differences can also influence the way participants understand and react to lesson material. These findings provide insight into how appropriate time management can increase the effectiveness of learning in LKP by taking into account the needs and characteristics of participants from various age ranges.

Acne vulgaris in black pediatric patients: clinical presentation, treatment patterns, and unique needs.

Acne vulgaris is a common dermatological diagnosis observed in pediatric patients with skin of color, often resulting in scarring, keloid formation, and post-inflammatory hyperpigmentation, significantly impacting their quality of life. This exploratory retrospective chart review included 77 black pediatric patients seen at a tertiary care center for acne vulgaris between 2018 and 2023. We analyzed demographics, acne descriptors, and treatment modalities. The most common acne morphology was comedonal acne (83.6%), with 71% of the patients being female. Significant age differences were observed particularly for acne at the chin and overall face. Treatment regimens commonly prescribed included combinations of adapalene and benzoyl peroxide (22%), topical antibiotics, tretinoin, and benzoyl peroxide (34%). Given the higher risk of sequelae for patients with darker skin, it is crucial to address their unique treatment needs. This study highlights the distinctive characteristics of acne in black pediatric patients and calls for further research to enhance our understanding and treatment of this population. Limitations include the lack of direct patient interactions and reliance on chart data. Further studies are needed to compare acne presentation in skin of color of other populations, refining our knowledge of acne clinical presentation, complications, and treatment modalities for diverse patient populations.

Association of dietary saturated fatty acid intake with depression: mediating effects of the dietary inflammation index.

Diet and dietary inflammation play an important role in depression. The aim of this study was to assess the association of SFAs with depression risk and the mediating role of DII. Among 22, 478 U.S. adults (≥ 20, years old) according to the National Health and Nutrition Examination Survey (NHANES), univariate logistic regression, and multivariate logistic regression were used to evaluate the association between dietary intake of SFAs and the risk of depression. Dietary inflammation levels were evaluated using the DII. Mediation analysis was used to investigate the risk of DII and depression. The nonlinear relationship between SFAs and depression was assessed using restricted cubic spline (RCS). There was a significant difference in SFA 6.0 dietary intake between depression and non-depression individuals. After adjusting for potential confounders, multifactorial logistic regression results showed that SFA 8.0 (Q3 1.58 (1.09, 2.30), p-value = 0.017; Q4 1.55 (1.00, 2.42), p-value = 0.050) may increase the prevalence factor for depression, SFA 14.0 (Q3 0.67 (0.47, 0.94), p-value = 0.020) may decrease the risk of depression. There were sex and age differences in the effects of different subtypes of SFAs on depression. Dietary intake of SFA 12.0 content showed a nonlinear relationship with the risk of depression (p-value = 0.005). Furthermore, DII was recognized as a mediator of the association between SFAs and the risk of depression. The findings suggest that dietary intake of SFAs is associated with the risk of depression in relation to the chain length of SFAs, and this may be due to the mediating effect of DII.
