Mean cycloplegic refractive error in emmetropic adults – The Tehran Eye Study / Error refractivo ciclopléjico medio en adultos emétropes: estudio ocular de Teherán

Purpose: In children under 20 years, refractive development targets a cycloplegic refractive error of +0.5 to +1.5D, while presbyopes over 40 years generally have non-cycloplegic errors of ≥ +1D. Some papers suggest these periods are separated by a period of myopic refractive error (i.e., ≤ –0.50D), but this remains unclear. Hence, this work investigates the mean cycloplegic refractive error in adults aged between 20 – 40 years. Methods: In 2002 a cross-sectional study with stratified cluster sampling was performed on the population of Tehran, providing cycloplegic and non-cycloplegic refractive error data for the right eyes of 3,576 participants, aged 30.6 ± 18.6 years (range: 1–86 years). After grouping these data into age groups of 5 years, the refractive error histogram of each group was fitted to a Bigaussian function. The mean of the central, emmetropized peak was used to estimate the mean refractive error without the influence of myopia. Results: The mean cycloplegic refractive error at the emmetropized peak decreased from +1.10 ± 0.11D (95 % confidence interval) to +0.50 ± 0.04D before 20 years and remains stable at that value until the age of 50 years. The non-cycloplegic refractive error also sees a stable phase at 0.00 ± 0.04D between 15 – 45 years. After 45 – 50 years both cycloplegic and non-cycloplegic refractive error become more hypermetropic over time, +1.14 ± 0.12D at 75 years. Conclusions: The cycloplegic refractive error in adults is about +0.50D between 20 – 50 years, disproving the existence of the myopic period at those ages.(AU)

Food insecurity and unemployment as mediators of the relationship between the COVID-19 pandemic and psychological well-being in young South Africans with HIV.

BACKGROUND: Poor psychological well-being, including depression, anxiety, and low self-esteem, is both prevalent among young South Africans living with HIV and associated with poor HIV clinical outcomes. By impacting food insecurity and employment, the COVID-19 pandemic may have influenced psychological well-being in this population. This analysis sought to examine whether food insecurity and unemployment mediated the relationship between study cohort (pre- versus during-pandemic) and psychological well-being in our sample of young South Africans living with HIV. METHODS: This was a secondary analysis comparing baseline data from two cohorts of young South Africans ages 18-24 from the Cape Town and East London metro areas who tested positive for HIV at clinics (or mobile clinics) either before or during the COVID-19 pandemic. Baseline sociodemographic, economic, and psychological outcomes were analyzed through a series of bivariate logistic regression and mediation analyses. All data were analyzed in 2023 and 2024. RESULTS: Reported food anxiety, insufficient food quality, and insufficient food quantity were lower in the cohort recruited during the COVID-19 pandemic than those recruited before the pandemic (p < 0.001). Higher levels of food insecurity predicted higher depressive and anxiety symptoms and lower self-esteem. Food anxiety, insufficient food quality, and insufficient food quantity, but not unemployment, mediated the relationship between study cohort and depressive symptoms, anxiety symptoms, and self-esteem. CONCLUSION: Food insecurity may have decreased amongst our sample of young people during the COVID-19 pandemic. Our findings build on our understanding of how the psychological well-being of young people living with HIV was affected by the COVID-19 pandemic and may lend support to interventions targeting food insecurity to improve psychological well-being in this population.

Validation of VO2max Prediction Using International Formulae for Young Saudi Men.

Objectives: In this study, we aimed to assess the maximal oxygen uptake (VO2max) of young, healthy, non-athletic Saudi men using maximum graded exercise with instant breath-by-breath analysis and to compare this value to the predicted VO2max by international formulae. Methods: In this cross-sectional study, 88 young non-athletic normal-weight Saudi subjects were recruited from Eastern Province of Saudi Arabia with mean age (21.3 ± 1.5 years), weight: (64.7 ± 7.5 kg), height: (172.3 ± 6.1 cm) and body mass index: (21.8 ± 2.1). All subjects were interviewed and examined for eligibility, after which they performed maximum graded exercise testing on a treadmill to obtain VO2max. The predicted VO2max was also generated using the following formulae (Edvardsen, Fairbarns, FRIENDS, Hansen, and Jones). Results: The mean measured VO2max was 41.9 ± 7.2 ml/kg/min. While the predicted VO2max using the formulae were: Edvardsen = 66.8 ± 7.9, Fairbarns = 64.1 ± 4.7, FRIENDS = 53.5 ± 2.2, Hansen = 42.8 ± 0.54, and Jones = 50.9 ± 5.1 ml/kg/min. There was a significant difference between all the predicted VO2max and the measured one using the paired t-test (P < 0.001), except for the Hansen's predicted value (P = 0.212). The effect size index (Cohen's d) for the comparison of Hansen's VO2max and measured VO2max was trivial and equal to 0.13. The Bland-Altman test showed good agreement between the measured and Hansen's predicted VO2max. Conclusion: This study demonstrated the mean VO2max value of young, healthy, and non-athletic Saudi men. This value was lower than Western values, which might be due to low physical activity or racial differences. Most international formulae overestimate the VO2max in this population, except for the Hansen equation. Therefore, Hansen's predicted VO2max might be the best available reference value for the diagnosis and prognosis of young Saudi individuals undergoing maximum exercise testing.

Economic Evaluation of a Novel Treatment of Attention-Deficit/Hyperactivity Disorder in US Motor Vehicle Drivers.

Background: Attention-deficit/hyperactivity disorder (ADHD) affects approximately 4.4% of US adults. ADHD is associated with high-risk driving behavior and costly motor vehicle accidents. DYANAVEL XR (DXR) (Tris Pharma, Inc.) is a once-daily fast-acting amphetamine developed for ADHD treatment. A randomized controlled trial showed that DXR patients were 43% less likely to crash during a driving simulation than individuals taking placebo. Study outcomes suggest a DXR crash rate similar to that of a driver without ADHD, while patients treated with the current standard of care (SOC) have a 52% higher crash risk than non-ADHD drivers. Objective: The aim was to evaluate the economic benefits attributable to improved driving abilities and avoided crashes in DXR patients compared with patients treated with the SOC or those who are untreated. Methods: A cost-impact model estimated 1-year crash-related cost outcomes for DXR-treated patients compared with SOC-treated and untreated ADHD patients. SOC was assumed to consist of a combination of short-, intermediate-, and long-acting ADHD stimulant and non-stimulant medications. DXR crash risk was assumed equivalent to the non-ADHD population risk, as supported by trial data. Crash risk for untreated and SOC-treated ADHD patients were assumed to be 99% and 52% higher than the general US population, respectively. Model outcomes included the cost impact (medication- and crash-related costs) and the number of crashes, injuries, and fatalities avoided with DXR. Results: Treatment with DXR would avoid 0.82 crashes, 0.016 injuries, and 0.036 fatalities per year compared with untreated patients, and 0.036 crashes, 0.007 injuries, and 0.0001 fatalities per year compared with SOC-treated patients. Compared with a population of 25% SOC-treated patients and 75% untreated patients, DXR use would save an average of 4581 p e r p e r s o n p e r y e a r a c r o s s a l l a g e g r o u p s w h e n p r i c e d a t 80 per month, assuming all SOC-treated and untreated patients utilized DXR. When the value of quality-of-life improvement is considered, savings increase over 7-fold. Discussion: Outcomes suggest that DXR may be an economically beneficial treatment compared with SOC for ADHD patients. Conclusions: The economic model showed that DXR is cost-saving compared with no treatment and SOC by reducing the number of motor vehicle crashes in the ADHD population.

Co-designing a vaping cessation program for Australian young adults: A conceptual model.

INTRODUCTION: Australian young adults (YA) report difficulties in quitting vaping. This study sought to understand what a vaping cessation program should look like from the perspective of current and former vapers, and professionals/experts involved in this health space, to inform the development of a conceptual model. METHODS: Data collection was informed by Social Cognitive Theory using co-design methodology to explore vaping cessation. Interactive workshops and semi-structured interviews were held online between March 2023-January 2024, with data from participants' narratives and written materials thematically analysed. RESULTS: YAs (18-24 years) identifying as current or former vapers (n=15) and health professionals/experts'(n=13) insights informed the model framework, incorporating three main elements based on environmental, personal and behavioural factors shaping vaping cessation. Four design considerations were identified; the program needs to be affordable, accessible, appropriate and adaptable. YAs expressed a strong preference to share their quitting journey with peers, endorsing a digital forum providing a hybrid framework of support. CONCLUSIONS: Vaping cessation is nuanced and complex requiring a multi-faceted approach targeted to the specific needs of the young adult population. IMPLICATIONS: The findings can be used to inform the development of a vaping cessation program tailored to young adults in Australia and other similar contexts. Young adults perceived sharing the quitting journey and being inspired by the lived experience of others as critical components for successful vaping cessation. Social Cognitive Theory is demonstrated to be a valuable behaviour change framework for understanding vaping cessation and should be considered in future research of intervention development.

Problematic social media use and vaping among Mexican-American college students.

Introduction: Social media use and vaping nicotine are highly prevalent in the daily lives of young adults, especially among Mexican-American college students. The excessive and compulsive use of social media platforms, coupled with the urge to stay continuously connected, can lead to problematic social media use. To date, no studies have explored the impact of problematic social media use on the daily patterns of vaping among this vulnerable population. Methods: In Spring 2023, we employed Ecological Momentary Assessment over a period of 14 days to collect real-time daily data on participants' social media use and vaping behaviors via a mobile phone-based application. Participants were 51 Mexican-American college students aged 18-25 years, 72.5% female, who were current vapers. We used generalized linear regression models to examine differences in vaping behaviors among participants with and without problematic social media use. All regression models adjusted for age, sex, and SES. Results: Participants with problematic social media use vaped on an average of 5.9 days compared to 5.7 days reported by those without problematic social media use (p < .05). Problematic social media use is associated with more frequent daily vaping [b = 0.03; 95% CI: 0.02-0.05], increased number of days vaping [b = 0.14; 95% CI: 0.07-0.20], and vaping higher nicotine concentrations [b = 0.08; 95% CI: 0.03-0.14]. Conclusion: Results suggest that problematic social media use significantly increases the risk of daily vaping among Mexican-American college students. Findings highlight the need to strengthen digital resilience and social media literacy to help college students navigate and mitigate the risks of social media.

Tackling anxiety through innovation: Development and pilot study of an in-the-moment messaging intervention for young adults.

Objective: Anxiety disorders are highly prevalent around the world and are associated with significant disability, comorbidity and costs to society. Digital tools have the potential to deliver equitable, convenient and sustainable interventions for anxiety. We aimed to co-design and pilot-test an in-the-moment intervention to help young people manage anxiety. Young people with lived experience of anxiety were recruited to participate in co-design workshops with the results informing the development of the Tackling Anxiety through Innovation (TAI) intervention. TAI delivers personally tailored messaging prompting engagement in self-care behaviours at times of high anxiety/stress. Methods: Young people aged 16 to 24 years were recruited into a four-week pilot study. Participants completed the Depression Anxiety Stress Scale - 21 Items (DASS-21) at baseline and four-week follow up, as well as a survey to assess the acceptability of the intervention and its components. Results: Participants (n = 24) reported the intervention to be highly acceptable and useful. Participants scheduled an average of eight events over the 4 weeks. DASS-21 scores improved significantly from baseline to follow up: anxiety (mean difference 2.42 (SD = 3.65), p = 0.004), depression (3.79 (SD = 3.65), p < 0.001) and stress (3.50 (SD = 3.30), p < 0.001). Participants particularly liked the ability to personalise the messages, the timing and format of the messages, and the reminders to engage in helpful behaviours. Conclusions: This study adds to the evidence for the use of digital tools in delivering tailored anxiety self-management support to young people. Further refinement and expansion of the intervention are needed to determine its efficacy on a larger scale.

Clinico-epidemiological characteristics of adolescents and young adults living with HIV in Ghana.

Introduction: sub-Saharan Africa is experiencing a boom in the number of adolescents and young adults living with HIV (AYALHIV). Existing HIV intervention programs are mainly for children and adults living with HIV, with little attention paid to AYALHIV. Characterizing this population is necessary for planning, and designing, AYALHIV-centered HIV intervention programs. Methods: a retrospective single-center, hospital-based chart review was conducted at the largest HIV clinic in Ghana. We examined routinely collected data for AYALHIV (aged 10-24 years) on antiretroviral therapy (ART) for at least 1 year and in active care from 1st January to 31st December 2019. Data was collected using a structured data extraction form. The Chi-square and the Student´s t-test were used to compare characteristics between adolescents and young adults. Results: of 252 AYALHIV, 68% (172/252) were adolescents with a median age of 17 years (IQR 13-19); 32% were young adults with a median age of 22 years (IQR: 20-24). Most (56.7% (143/252)) AYALHIV were female. Almost 40% were orphans. Eighty-six percent of AYALHIV had HIV type I infection. The commonest mode of HIV acquisition among adolescents was vertical transmission (70.5%) and that among young adults was via unprotected sex (31.3%). Eighty-eight percent (88%) of AYALHIV were on non-nucleoside reverse transcriptase inhibitors-based regimen. The viral suppression rate among AYALHIV was 78%. Conclusion: the study shows there is a growing population of AYALHIV most of which are adolescents. About two-fifths were orphans. Policymakers and HIV programs should ensure AYALHIV-centred interventions are developed for this vulnerable population.

Exploring the Role of Sustainable Development Goals in Enhancing Courage, Proactive Career Behaviors, and Life Satisfaction.

Understanding the current challenges addressed in the goals of the 2030 United Nations Agenda can influence career choices, encouraging individuals to pursue careers that contribute positively to addressing them. This study examines the association between the propensity to consider the Sustainable Development Goals (SDGs) in relation to future educational and career paths, courage, proactive career behaviors and life satisfaction, and the mediating role of courage and proactive career behaviors on the association between the propensity to consider the SDGs in relation to future educational and career paths and life satisfaction. The study sample consisted of 314 Italian university students. The serial multiple mediation model was used to examine the direct, indirect, and total effects. The results showed that the propensity to consider SDGs in relation to future educational and career paths, through courage and proactive career behaviors, has a positive impact on life satisfaction. The findings of this study have led to several actionable policy recommendations. These advocate for the integration of activities related to modules on the SDGs into their curricula. In addition, practical implications for career guidance interventions are proposed to consider the role of the SDGs in future career planning.

Perfectionism and Emotion Regulation in the Study of Suicidal Ideation in Portuguese Young Adults.

Suicide is a serious public health problem worldwide, being the culmination of a process that normally begins with suicidal ideation. Therefore, it is important to assess suicidal ideation and know its risk factors. The association between perfectionism and suicidal ideation has been widely debated in the literature. However, knowledge about the role of emotion regulation in this relationship is scarce. The main objective of this investigation was thus to study the role of emotion regulation in the relationship between perfectionism and suicidal ideation in young adults. A sample of 224 Portuguese young adults was recruited through an online form which assessed suicidal ideation, perfectionism, and emotion regulation. The results showed a positive relationship between suicidal ideation and emotion regulation difficulties. There was also a positive association between emotion regulation difficulties and perfectionism, especially regarding the strategies and dimensions of maladaptive perfectionism. The relationship between perfectionism and suicidal ideation was fully mediated by emotion regulation difficulties. Increases in emotion regulation difficulties from increased perfectionism could contribute decisively to increasing the risk of suicidal ideation. Thus, the assessment of perfectionism and emotion regulation difficulties can promote the prevention and psychological interventions for suicidal behavior.

Physical Activity, Sedentary Behavior, and Body Image among Young Adults in Hong Kong: A Cross-Sectional Study.

The COVID-19 pandemic has considerably impacted the health and lifestyle of various populations worldwide, leading to decreased physical activity, increased sedentary behavior, and increased health problems. This study aimed to investigate Hong Kong young adults' physical activity, related behaviors, and perceptions of body image during the pandemic. A cross-sectional online survey of young adults aged 18-29 was conducted from February to March 2021 using the well-validated Multidimensional Body Self-Relations Questionnaire (MBSRQ). Among 408 respondents, 52.5% had a normal weight in the BMI range, 45.1% engaged in ≥8 h of sedentary behavior daily, 77.2% engaged in no regular or inadequate physical activity (<2.5 h/week), and only 22.3% joined a fitness club. BMI, regular physical activity, and joining any fitness club/class were significantly associated with the most factors or additional subscales. A multiple linear regression model showed that the underweight respondents (reference group: normal) (ß = -0.26, 95% CI: -0.41 to -0.12) were less likely to have high scores of fitness orientation. The respondents who engaged in regular physical activity <2.5 h/week (ß = 0.42, 95% CI: 0.29 to 0.54), engaged in regular physical activity ≥2.5 h/week (ß = 0.99, 95% CI: 0.84 to 1.14) (reference group: no regular physical activity), and joined a fitness club/class (ß = 0.32, 95% CI: 0.18 to 0.45) were more likely to have a high score of fitness orientation. Local governments, non-governmental organizations, schools, and community centers should establish appropriate strategies and activities in order to sufficiently encourage and support young adults' physical health and well-being.

Destigmatizing Palliative Care among Young Adults-A Theoretical Intervention Mapping Approach.

Background: In medicine, stigmatization pertains to both afflicted individuals and diseases themselves but can also encompass entire medical fields. In regard to demographic change and the rising prevalence of oncological diseases, palliative care will become increasingly important. However, palliative care faces multiple stigmas. These include equating of palliative care with death and dying. A timely integration of palliative care would have the potential to alleviate symptom burden, diminish the risk of overtreatment, and thus save healthcare-related costs. Several interventions have been developed to destigmatize palliative care. However, they have mainly focused on the general public. Aim: The aim of this work is to develop a theoretical framework for an interventional campaign targeted at young adults to systematically destigmatize palliative care. Methods: The basis for the development of the campaign is a systematic review conducted by our working group that assessed the perception and knowledge of palliative care of young adults aged 18 to 24 years. To design a possible intervention, the Intervention Mapping approach was used. Results: The target group of young adults can be effectively reached in secondary schools, vocational schools, and universities. The target population should be able to discuss the content of palliative care and openly talk about death and dying. At the environmental level, palliative care should be more present in public spaces, and death and dying should be freed from taboos. Within an intervention with palliative care experts and patients serving as interventionists, these changes can be achieved by incorporating evidence-based methods of behavioral change. Conclusions: An early engagement with palliative care could contribute to the long-term reduction of stigmas and address the demographic shift effectively. A multimodal intervention approach comprising knowledge dissemination, exchange, and media presence provides an appropriate framework to counter the existing stigmatization of palliative care within the peer group of young adults.

Implementing a Pulmonary Telerehabilitation Program for Young Adults with Post-COVID-19 Conditions: A Pilot Study.

BACKGROUND: Several studies have shown that pulmonary telerehabilitation (PTR) improves respiratory capacity. However, there is little evidence of its effectiveness in youth with post-COVID-19 conditions (PCC). This study analyzed the effects of a PTR program on young adults with PCC. METHODS: Sixteen youths were randomly assigned to a control group (CG) or an experimental group (EG), with eight participants each. The EG participated in a PTR program that included twelve remote, asynchronous four-week sessions with diaphragmatic breathing and aerobic exercises. Vital signs (SpO2, HR, RR, BP), physical capacity (sit-to-stand test), cardiorespiratory capacity (6-Minute Walk Test), and perceived exertion (Borg scale) were assessed in both groups. RESULTS: Statistical analyses showed a significant decrease in RR and HR (p < 0.012) and an increase in SpO2 (p < 0.042), physical (p < 0.012), and respiratory (p < 0.028) capacity. Perceived effort decreased significantly in both groups (CG: p < 0.006; EG: p < 0.001) only for physical but not for cardiorespiratory capacity (p < 0.106). There were no statistical changes registered in BP (p > 0.05). CONCLUSIONS: The PTR program, which includes respiratory and aerobic exercises, is feasible and effective in improving physical and cardiorespiratory capacity in young people with PCC, as well as reducing HR, RR, and dyspnea.

Assessing Misophonia in Young Adults: The Prevalence and Psychometric Validation of the MisoQuest Questionnaire.

Background/Objectives: Misophonia, characterized by strong emotional reactions to specific sounds, poses significant challenges, particularly in academic settings. This study aimed to examine the psychometric properties of the Brazilian version of the MisoQuest in a sample of high school and university students. The primary objective was to assess its reliability and structural validity to enhance understanding of misophonia in young adults. Methods: A total of 549 students (Mean age = 23.2 years, SD = 9.3; 285 females, 260 males, 4 individuals who did not disclose their gender) participated. Both exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were employed to evaluate the MisoQuest. Fit indices for unifactorial and trifactorial models were compared. Internal consistency was assessed using Cronbach's alpha. Results: The EFA suggested a dominant single-factor structure with high factor loadings (ranging from 0.60 to 0.79). However, the CFA revealed excellent fit for both unifactorial (CFI and TLI = 1.00, RMSEA close to zero) and trifactorial models (CFI and TLI = 1.00, RMSEA = 0.037). The MisoQuest demonstrated high internal consistency (Cronbach's alpha = 0.93). Additionally, 4.5% of participants were identified as positive for misophonia based on a predefined cutoff score of 61. Conclusions: The Brazilian version of the MisoQuest is a reliable and valid tool for assessing misophonia. These findings suggest that the instrument may capture multiple dimensions of the disorder. Given the observed prevalence of misophonia and its impact on students, early identification and tailored interventions are crucial for providing adequate support. Further research is needed to refine the tool and expand its clinical utility.

Relating to the Body Under Chronic Cancer Threat: Implications for Psychosocial Health Among Adolescents and Young Adults with Cancer Predisposition Syndromes.

Purpose: Adolescents and young adults (AYAs) with cancer predisposition syndromes often experience significant physical and psychosocial burdens. These burdens include cancer worry and potentially distressing bodily changes due to risk-reducing procedures (e.g., mastectomy) or cancer treatments. This qualitative-descriptive study explored how AYAs with Li-Fraumeni syndrome (LFS) relate and adjust to their bodies under the chronic threat of cancer. Methods: Participants were enrolled in the National Cancer Institute's LFS study. This analysis included 42 AYAs with LFS aged 15-39 years at enrollment who completed one or two telephone interviews that explored LFS-related bodily experiences and challenges. Transcripts were thematically analyzed. Results: The majority of participants (n = 26/42, 62%) had ≥1 primary cancer. The mean age at first cancer diagnosis was 21 years (range = 0.5-35 years). Participants described challenges relating to the body due to frequent self-monitoring, whole-body magnetic resonance imaging scans, risk-reducing surgeries, and/or cancer treatments. Heightened body awareness and vigilance not only prompted self-protective behaviors but also triggered worry and distress. AYAs coped with bodily changes and concerns by seeking doctors' reassurance, engaging in health-protective behaviors, and reframing perceptions of their altered bodies. Conclusion: Findings suggest AYAs with cancer predisposition syndromes such as LFS experience difficulties relating and adjusting to the body that may compromise psychosocial health. Our results demonstrate that these difficulties may arise across the time course of genetic disease, including before a cancer diagnosis. Clinicians might support AYAs by conducting routine psychosocial risk assessments, providing anticipatory guidance regarding body-related challenges, sharing peer support resources, and referring to mental health providers, as needed.

Collisions and Perceptions of Cyberbullying: Comparison of Intergenerational Experiences.

With regard to negative consequences, cyberbullying is recognized as one of the most traumatic types of cyber aggression. The aim is to study the specific features of adolescents and youth's cyberbullying experience in the role of an aggressor, victim or bystander, as well as awareness on the part of parents of adolescents. A total of 3395 adolescents, youth and parents filled out specially designed questionnaires. Older adolescents turned out to be at higher risk of cyberbullying. In two-thirds of cases, cyberbullying is related to real-life incidents. Aggressors are motivated by domination and entertainment, primarily employing strategies of social exclusion, harassment and denigration. As victims of cyberbullying, younger adolescents turn to their parents and friends for social support, whereas older adolescents and young adults are more likely turn to their peers. In the role of a bystander, almost half of younger adolescents and about a third of older adolescents and young adults choose the prosocial strategy of protecting a victim. The parents often underestimate the experience of encountering cyberbullying or find it difficult to assess such experience. The identified risk groups and strategies and the lack of parents' awareness are important to take into account when drawing up cyberbullying prevention programs.

Beyond the Screen: A Comprehensive Analysis of Emotional Skills and Social Networking in French Young Adults.

(1) Background: This study investigates the influence of social networks on young adults, focusing on both positive and negative impacts. It considers problematic social networking site use (PSNSU), emotional intelligence, empathy, and the phenomenon of Fear of Missing Out (FoMO). (2) Methods: A comprehensive online survey was conducted with 442 participants aged 18 to 30 years that used various psychometric tools to assess emotional intelligence, empathy, internet and social media use, and FoMO. (3) Results: The study revealed that young adults display low competencies in emotional intelligence and empathy, with a tendency towards problematic internet and social media use. High FoMO scores were observed, correlating with negative internet use outcomes. Gender differences in these aspects were also explored. (4) Conclusions: The findings suggest a complex interaction between social network use, emotional skills, and FoMO that impacts young adults' mental health and social behaviors. This study highlights the need for a nuanced understanding of these relationships and their implications for well-being and social interaction in the digital age.

Problematic Pornography Use, Mental Health, and Suicidality among Young Adults.

The relationship between suicidality and problematic pornography use (PPU) is not clear, and the limited research data that exists show contradictory results. The present study aims to explore the associations between these two variables in a sample of young adults, taking into account gender differences and the role of loneliness, emotional states, and well-being. A total of 332 national and international students (60% female) at an Italian University with a mean age of 23 years (SD = 2.84) completed an anonymous online survey during the period from March 2023 to May 2023. The results show that PPU was associated with higher levels of anxiety, depression, stress, loneliness, and suicide ideation, as well as lower life satisfaction. Gender comparison analysis revealed significantly higher scores for PPU and loneliness among men, while women scored higher in stress, anxiety, and life satisfaction. Significant correlations between PPU and suicidal ideation and having a suicide plan were established for female participants despite their lower scores in PPU. Multiple regression analysis revealed that PPU and its interaction with gender were both significant predictors of suicidal ideation. Future attention should be paid to how young women may be influenced by exposure to sexually explicit materials, while always considering the role of loneliness.

The Temporal Change in Ionised Calcium, Parathyroid Hormone and Bone Metabolism Following Ingestion of a Plant-Sourced Marine Mineral + Protein Isolate in Healthy Young Adults.

Background: An increase in plant-sourced (PS) nutrient intake is promoted in support of a sustainable diet. PS dietary minerals and proteins have bioactive properties that can affect bone health and the risk of fracture. Methods: In a group randomised, cross-over design, this study evaluated the post-ingestion temporal pattern of change in arterialised ionised calcium (iCa), parathyroid hormone (PTH), C-terminal crosslinked telopeptide of type I collagen (CTX) and procollagen type 1 amino-terminal propeptide (P1NP) for 4 h following ingestion of a novel supplement (SUPP) containing a PS marine multi-mineral + PS protein isolate. A diurnally matched intake of mineral water was used as a control (CON). Results: Compared to baseline, the change in iCa concentration was 0.022 (95% CI, 0.006 to 0.038, p = 0.011) mmol/l greater in SUPP than CON, resulting in a -4.214 (95% CI, -8.244 to -0.183, p = 0.042) pg/mL mean reduction in PTH, a -0.64 (95% CI, -0.199 to -0.008, p = 0.029) ng/mL decrease in the biomarker of bone resorption, CTX, and no change in the biomarker of bone formation, P1NP. Conclusions: When used as a dietary supplement, or incorporated into a food matrix, the promotion of PS marine multi-mineral and PS protein isolates may contribute to a more sustainable diet and overall bone health.
