Study purpose: this study aims to analyze QOL and psychosocial impact on patients with blood disorders.

Methods: A cross-sectional survey design is adopted in this study. The survey questionnaire included SF-36 form for measuring quality of life (QOL), along with psychosocial impact assessment scale. Adult patients with different types of blood disorders were recruited for the survey. Out of the 417 responses received, 389 were considered for data analysis and the remaining were avoided due to incomplete data.

Results: In terms of psychosocial impact scales, the highest mean is observed for financial stress (4.09 ± 1.22), followed by social exclusion (3.76 ± 1.19) and relationship challenges (3.31 ± 1.18). Among the QOL scales, the highest mean was observed for pain (3.81 ± 1.17), followed by physical functioning (3.68 ± 1.12). Statistically significant differences (p < 0.05) were observed among the participants groups characterized by age and type of disorder. Strong positive correlations between social exclusion and general health (r = 0.513), as well as pain and relationship challenges (r = 0.735) were observed.

Conclusion: Given the existing challenges in social exclusion, poor awareness, and support there is a need to develop comprehensive and personalized treatment plans integrating physical and mental support, awareness creation, and financial support.

Background: Self-compassion is a prevalent factor that has been explored in eating behaviour and weight loss literature. The present study explored the potential relationship between self-compassion and reasons individuals stop eating.

Method: Two hundred and eighty-three participants were recruited from social media platforms and a research participation scheme at a university in the West Midlands, UK, and completed questionnaires on self-compassion and reasons individuals stop eating.

Results: The findings suggested that self-compassion was negatively associated with decreased food appeal, self-consciousness, and decreased food priority, whilst being positively associated with physical satisfaction.

Conclusion: Self-compassion plays a prevalent role in the reasons individuals stop eating, and future research should continue exploring the effect of self-compassion on eating behaviour regulation.

Background: Proteins are essential for the maintenance, repair, and growth of muscle mass. This is particularly important for master athletes because aging has been associated with loss of muscle mass, function, and strength. Moreover, the timing of intake has been shown important for the best protein utilization. Aim: To analyze timing, quantity, and source of dietary protein in competitive master athletes according to current recommendations. Methods: Twenty-one male master swimmers (47.9 ± 10.0 years; 79.2 ± 6.5 kg; 179.1 ± 5.5 cm; 23.5 ± 4.9% body fat; 73.3 ± 4.2% lean mass) participated in this cross-sectional study. Protein intake was analyzed based on 7-day food records, regarding quantity, timing, and sources of intake. Protein intake was evaluated according to current international sports nutrition guidelines, including the International Society of Sports Nutrition Position Stand. Body fat (%) and lean mass (%) were evaluated using dual-energy X-ray absorptiometry. Results: Participants' mean protein intakes were 1.9 ± 0.5 g/kg/day, 0.6 ± 0.2 g/kg/meal post-training, and 33.5 ± 23.9 g during the pre-sleep period. Daily intake was within the recommended values of 1.4 and 2.0 g/kg/day (p = 0.01 and 0.147, respectively). Mean pre-sleep intake was within the recommendation values of 30-40 g (p = 0.28 and 0.147, respectively). Most of the daily protein intake was consumed at lunch (66.7 ± 6.9 g) and dinner (48.0 ± 4.5 g). Regarding protein sources, intakes from animal, vegetal, and supplements were, respectively, 65.7%, 29.2%, and 5.1%. Conclusion: Master swimmers presented a total protein intake within the recommendations for a daily basis, but the majority of intake was at lunch and dinner. Protein intake could be better distributed throughout the day to optimize protein synthesis. Guidance on daily protein intake distribution should be reinforced in clinical practice.

The purpose of this content analysis was to ascertain what nutrition advice or information is freely available on a global scale through each National Governing Body (NGB) webpage. In total, 52 NGBs and the International Federation of Gymnastics (FIG) were identified based on the FIG November 2022 world rankings for both male and female athletes in all disciplines. Concluding observations were that publicly available nutrition advice is limited across the global gymnastics platforms. Conflicting advice was also identified within some organisations surrounding the weighing of gymnasts for hydration purposes and some macronutrient discrepancies thus, potentially impacting the clarity of the message for the reader. Based on this content analysis recommendations for future practice include providing clarity and provision of tools to measure hydration, dietary recommendations should be clear and specific, and a more centralised approach to standardise advice and publicly available information.

Background: Geographically Isolated and Disadvantaged Areas (GIDA) are communities physically and socioeconomically separated from mainstream society (non-GIDA) and lack comprehensive nutrition and health assessments. Aim: This study aimed to assess the nutritional and health status and determine the factors associated with chronic energy deficiency (CED) and overweight/obesity among adults, 20-59 years old, residing in GIDA and non-GIDA. Methods: Data of the 20,381 adults collected in the Expanded National Nutrition Survey were analyzed. Multivariate logistic regression analyses were performed to determine the predictors of CED and overweight/obesity. Results: Chronic energy deficiency and current smoking were significantly higher in GIDA, while overweight/obesity, alcohol consumption, elevated blood pressure, and insufficient physical activity were higher in non-GIDA (p < 0.001). Higher odds of CED was associated with food insecurity (adjusted odds ratio [AOR]: 1.5, p < 0.001; AOR: 1.3, p < 0.001) and current smoking (AOR: 1.4, p = 0.001; AOR: 1.3, p < 0.001) in both GIDA and non-GIDA while poor wealth (AOR: 1.5, p < 0.001) only in non-GIDA. Higher odds of overweight/obesity was associated with higher age ≥30 years (AOR: 2.1, p < 0.001; AOR: 1.9, p < 0.001), being female (AOR: 1.7, p < 0.001; AOR: 1.3, p < 0.001), with grade level completed (AOR: 1.7, p = 0.004; AOR: 1.2, p = 0.038), urban residence (AOR: 1.2, p = 0.035; AOR: 1.3, p < 0.001), hypertension (AOR: 2.4, p < 0.001; AOR: 2.3, p < 0.001), and insufficient physical activity (AOR: 1.1, p = 0.020; AOR: 1.1, p = 0.027) in both GIDA and non-GIDA. Conclusions: Malnutrition affects GIDA in almost the same magnitude. The double burden of malnutrition and health inequity in GIDA underscores the greater need for comprehensive policies and stronger programs directed toward underserved areas.

Background and aims: This exploratory observational prospective study aimed to evaluate fat-soluble vitamin plasma levels during hospital admission and its relation with the development of malnutrition and complications in polytrauma patients, considering the protocolized multivitamin supplementation during intensive care unit (ICU) admission.

Methods: In 49 well-nourished polytrauma (injury severity score ≥ 16) patients admitted to the ICU of two level-1 trauma centers, vitamin A, D, and E levels were assessed weekly during hospital stay. All patients received multivitamin supplementation during ICU stay. Linear mixed-effect models were used to assess a trend in vitamin levels over time during hospital stay. Mixed-effects logistic regression analysis was performed to relate vitamin concentrations with malnutrition, defined as a subjective global assessment score ≤5, and complications.

Results: Vitamin A levels increased 0.17 µmol/L per week (95% confidence interval 0.12-0.22, p < 0.001), vitamin D levels increased 1.49 nmol/L per week (95% confidence interval 0.64-2.33, p < 0.01), vitamin E levels increased 1.17 µmol/L per week (95% confidence interval 0.61-1.73, p < 0.001) during hospital stay (29 ± 17 days). Vitamin levels were not related to malnutrition or complications during hospital stay.

Conclusion: Vitamin A, D, and E levels increased due to supplementation during hospital admission. Plasma levels of vitamins A, D, and E do not seem to be useful as biomarkers for the nutritional status of polytrauma patients during hospital stay. No correlation with complications could be demonstrated.

Purpose: This study aims to assess the effectiveness of ChatGPT in remote learning among medical students. Methods: This cross-sectional survey study recruited 386 medical students from three public universities in Saudi Arabia. Participants completed an online questionnaire designed to assess perceptions of ChatGPT's effectiveness in remote learning. The questionnaire included Likert scale questions to evaluate various aspects of ChatGPT's support in remote learning, such as personalized learning, language and communication skills, and interactive quizzing. Data were analyzed using SPSS, employing descriptive statistics, independent samples t-tests, one-way ANOVA, and Cronbach's alpha to evaluate reliability. Results: Participants mostly used ChatGPT on a weekly (43.2%) or daily (48.7%) basis, primarily on personal computers (62.5%). Mean scores for ChatGPT's support in remote learning were high for personalized learning (4.35), language and communication skills (4.23), and interactive quizzing and assessments (4.01). Statistically significant differences were found based on gender for interactive quizzing (p = .0177) and continuity of education (p = .0122). Conclusion: Despite certain challenges and variations in perceptions based on gender and education level, the overwhelmingly positive attitudes toward ChatGPT highlight its potential as a valuable tool in medical education.

Background: While many studies have been published on nutrient intake assessment for performance improvement and deficiency prevention in single-sport athletes, few studies have addressed nutrient intakes in athletes from a various sports.

Aim: The aim of this study was to determine whether Japanese college athletes meet the Dietary Reference Intakes (DRIs) and sports nutrition recommendations (SNRs).

Methods: Dietary intake was assessed in 1049 Japanese college athletes from a variety of sports using a validated brief-type self-administered diet history questionnaire. The prevalence of inadequate intakes was estimated by comparing the DRIs and SNRs.

Results: For protein, riboflavin, niacin, vitamins B-6, vitamins B-12, folate, magnesium, zinc, and copper, <10% of females and males consumed diets that fell below the estimated average requirement (EAR) in the DRIs. A large proportion of female and male college athletes demonstrated intakes that were below the EAR for vitamin A (7.8% and 19.0%, respectively), thiamin (10.4% and 23.9%, respectively), calcium (20.4% and 29.7%, respectively), and iron (24.2% and 2.5%, respectively). Regarding DG for chronic disease prevention in the DRIs, over half of both female and male athletes exceeded the DG for saturated fat acid and sodium, and fell below the DG for dietary fiber. Few of both female and male had intakes below the SNRs for protein and carbohydrates.

Conclusion: The results of the present study reveal the nutrient intake status of Japanese college athletes by comparing the DRIs and SNRs. Most meet the SNRs for optimal performance, but not the DRIs for health.

Study purpose: This study aims to assess the effectiveness of ChatGPT in critical thinking skills among medical students.

Methods: This cross-sectional survey study recruited 392 medical students from three public universities in Saudi Arabia. Participants completed an online questionnaire assessing perceptions of ChatGPT's impact on critical thinking skills. Data were analyzed using SPSS, employing descriptive statistics, t-tests, analysis of variance, and Cronbach's alpha to evaluate reliability.

Results: Significant gender-based differences were found in perceptions of ChatGPT's efficacy, particularly in generating diverse perspectives (P = 0.0407*) and encouraging questioning (P = 0.0277*). Reflective practice perceptions varied significantly by age (P = 0.0302*), while academic backgrounds yielded significant differences across all factors assessed (P < 0.0001*). Overall, 92.6% believed integrating ChatGPT would benefit critical thinking skills. Most participants (N = 174) strongly agreed that ChatGPT improved critical thinking.

Conclusion: Integrating ChatGPT into medical education could offer valuable opportunities for fostering critical thinking abilities, albeit with the need for addressing associated challenges and ensuring inclusivity.
