Background: Estimating the actual impact of eating out on calorie intake poses challenges due to the potential endogeneity of eating out. Controlling for endogeneity is essential to obtain more precise estimates. Aim: This study estimates the effect of eating out on calorie intake, specifically focusing on dinner among the three daily meals. Methods: The endogenous treatment effect model is employed, utilizing restricted-access data from the 2017 to 2020 Korea National Health and Nutrition Examination Survey. To aid model identification, daily precipitation is used as an instrumental variable influencing the decision to eat dinner out. Results: Eating dinner out results in an additional intake of 388.39 Kcal compared to eating at home, whereas the model that does not control for the endogeneity estimates a 261 Kcal increase. The increase in calorie intake from eating dinner out varies significantly depending on individual characteristics. Conclusion: Eating out leads to a substantial amount of calorie intake. Managing the frequency of eating out at a reasonable level could play a crucial role in preventing obesity.

Background: Although literature demonstrates controversial results regarding the association between selenium and glucose metabolism, no studies have specifically targeted a population with obesity even though this group is vulnerable to insulin resistance.

Aim: To evaluate the association between selenium biomarkers and insulin resistance in women with obesity.

Methods: This case-control study recruited 84 women with obesity and 129 with healthy weight (control). Selenium intake was assessed by 3-day food record. Selenium concentration in plasma, erythrocyte, and urine was assessed by inductively coupled plasma optical emission spectrometry. Serum glucose, insulin, and glycated hemoglobin (HbA1c) were assessed in a fasting blood sample. Homeostasis Model Assessment of Beta Cell Function (HOMA-β) and Homeostasis Model Assessment of Insulin Resistance were calculated according to standard methods.

Results: Women with obesity had higher dietary selenium intake in comparison to the control group (p < 0.001). Further, the plasma and erythrocyte concentrations were lower in individuals with obesity (p < 0.001), while selenium in urine was higher (p < 0.001) than in controls. No significant differences in insulin resistance markers were observed between groups. Selenium intake was positively associated with HOMA-β in both groups. In women with obesity, selenium intake was also positively associated with insulin and HbA1c, while in the controls the clearance of selenium was negatively associated with insulin and HbA1c. There was a positive correlation between dietary selenium intake, fasting insulin, HbA1c, and HOMA-β (p < 0.05).

Conclusions: Women with obesity present impaired selenium metabolism. Further, we observed an association between dietary selenium and markers of insulin resistance, which may reflect the possible negative action of selenium on insulin signaling.

Introduction: Lifestyle interventions aiming to reduce excess body weight have been focusing on individuals living with overweight or obesity. However, many health-related behaviors including eating are concordant in couples indicating they might share an obesity risk or support each other's weight loss efforts. Aim: The aim of this systematic review and meta-analysis of randomized controlled trials was to assess the weight change effects of lifestyle interventions targeting couples in a romantic relationship regardless of marital status or sexual preference compared to individuals or no intervention. Methods: Four databases (MEDLINE Ovid, Scopus, CINHAL, and mySearch: EBSCO-Discovery-Service-Tool) were systematically searched from inception until 26^th April 2021 with further email alerts. The risk of bias was assessed using the Critical Appraisal Skills Programme. Meta-analysis was conducted using the random-effect model to estimate the weighted mean difference with 95% confidence interval. Results: Seventeen studies were eligible for this review and 11 of them were included in the meta-analysis for weight change. Significant intervention effects were identified for body weight in couples' intervention vs. individual intervention (-2.25 kg, 95% CI-3.63 to-0.88), and vs. no intervention (-4.5 kg, 95% CI-6.62 to-2.38). Conclusion: This systematic review and meta-analysis was the first to investigate the effectiveness of lifestyle interventions targeting couples on weight loss, compared to interventions focused on individuals or standard care. The findings suggest that interventions aimed at couples lead to greater weight loss, though the results should be interpreted with caution due to the wide heterogeneity among the studies. Further research is needed with evidence-based study designs, targeting younger participants, and incorporating longer intervention durations and follow-up periods.

Study purpose: This study aims to critically evaluate ChatGPT's impact on cybersecurity in healthcare and education sectors.

The survey assessed perceptions of ChatGPT's impact on cybersecurity opportunities and challenges, with data analyzed using descriptive statistics and ANOVA to explore differences across professional roles.

Results: Healthcare professionals viewed artificial intelligence (AI) more favorably (mean scores 4.24 and 4.14) than those in education, who showed moderate enthusiasm (mean scores 2.55 to 3.54). Concerns over data privacy and the cost of securing AI were significant, with high mean scores of 3.59 indicating widespread apprehension.

Conclusion: A balanced approach to ChatGPT's integration that carefully considers ethical implications, data privacy, and the technology's dual-use potential is required.

Background: Telepharmacy has emerged as a vital tool in healthcare, allowing remote medication management, especially for patients in rural areas. Despite its growing adoption, there is limited empirical evidence on its effectiveness and patient experiences in diverse healthcare settings. Aim: This study aims to investigate telepharmacy and remote medication management through the lens of patients, shedding light on their attitudes, challenges, and preferences. Methods: A cross-sectional survey design is adopted in this study. Survey participants included outpatients aged above 18 years, accessing telepharmacy services from public hospitals in Saudi Arabia. The survey questionnaire focuses on evaluating patients' experiences and perspectives regarding telepharmacy services for remote medication management. Excluding incomplete responses resulted in a final sample of 403. Results: Participants reported positive experiences with telepharmacy, rating it moderately to very effective (Mean = 3.12-3.21) across various factors. Significant age-related differences were observed, with younger participants perceiving telepharmacy more favorably (P < 0.0001). Education levels did not significantly affect perceptions. Residential location also showed no significant impact. Patients suggested technical support and improved communication methods to enhance telepharmacy services. Implementing these suggestions increased patients' likelihood of future telepharmacy use. Conclusion: Telepharmacy, by utilizing telecommunication technology, offers a transformative approach to remote medication management, significantly improving patient care across various healthcare environments.

Background: Medical staff for indoor aesthetic sports such as acrobatics and tumbling (A&T) is often concerned with athletes' bone mineral density (BMD), serum vitamin D (SvD), and associated injury risks. Aim: To evaluate the relationship between BMD, SvD, and injury among A&T athletes. Methods: 42 (19 tops, 23 bases) female A&T athletes aged 19.6 (±1.17) years participated. Two samples of SvD were taken. Injury and BMD data were provided by support staff. Bivariate and multivariate analysis assessed relationships between and among variables. Results: Participants experienced a decrease in SvD (6.093 ± 10.973). Spine BMD was significantly higher in bases compared to tops (p = 0.039). BMD and SvD did not differ based on injuries sustained. Conclusion: Relationships between SvD, BMD, and injury were not identified. Positional differences in BMD may be related to the demands of each role. Participants possessed low SvD and high BMDs, which may provide useful information for medical staff.

Background: Several reports suggest potential cytotoxic effects of creatine, possibly due to its role in facilitating the formation of food-borne chemical carcinogenic compounds. Aim: This cross-sectional study aims to investigate the relationship between creatine consumption and various carcinogenic biomarkers in blood and urine among individuals aged 18 years and older, utilizing data from the 2013-2014 National Health and Nutrition Examination Survey (NHANES). Methods: Daily creatine intake was assessed using the Dietary Data databases, which were compiled from individual in-person 24-h food recall interviews. The concentrations of carcinogenic compounds (heterocyclic amines, acrylamide, and formaldehyde) were extracted from NHANES 2013-2014 Laboratory Data database. Results: The final analysis included 1763 adult respondents, of whom 907 (51.4%) were female. The mean daily creatine intake was 0.83 ± 0.77 grams (95% CI, from 0.80 to 0.87). Regression analysis revealed no significant relationship between daily creatine intake and most carcinogenic biomarkers, except for a significant correlation (Model 1) between creatine intake and acrylamide levels (B = -3.999, ß = -0.088, p = 0.05). Model 2 (demographics) confirmed a significant relationship between daily creatine intake and circulating acrylamide (B = -3.490, ß = -0.077, p = 0.02), as well as for blood levels of glycidamide (B = -2.992, ß = -0.068, p = 0.05) and urinary 2-Amino-1-methyl-6-phenylimidazo[4,5-b]pyridine (B = 0.190, ß = 0.088, p = 0.03). However, no correlation between creatine consumption and any carcinogenic biomarkers remained significant after adjusting for nutritional factors (Model 3) (p > 0.05). Conclusion: In conclusion, the consumption of dietary creatine may be considered safe and not associated with increased levels of above carcinogens in the general population.

Background: Global healthcare and nutrition policies have not eliminated the pressing public health issue of undernutrition, which remains a paramount public health concern in countries like India, coinciding with overweight and obesity, in the form of dual burden of malnutrition. Aim: This study delves into the rural-urban differential in undernutrition among reproductive-aged women in India for targeted policy interventions and to achieve universal health coverage. Methods: Data from the recent iteration of the National Family Health Survey (NFHS-5; 2019-21) were utilized to examine the factors influencing rural-urban differentials in women's undernutrition. A set of logistic regression and Fairlie's decomposition analysis are employed to identify the associated covariates and understand the factors driving these differentials. Results: The analysis reveals that rural women are significantly more vulnerable to undernutrition compared to urban counterparts, with factors such as education, wealth status, age, and dietary diversity playing key roles. The decomposition analysis of the rural-urban gap revealed that the variables considered in the study accounted for approximately 75% of the disparity. The difference in household wealth between rural and urban areas contributed about 63% of the explained gap, followed by educational status (16%), age group (11%), dietary diversity (8%), religion (5%), and media exposure (4%). Conclusion: The findings underscore the importance of targeted interventions addressing socio-economic inequalities to mitigate undernutrition among women in India. Enhancing access to education, improving economic opportunities, promoting dietary diversity, and challenging cultural norms are crucial steps towards achieving equitable nutritional outcomes and reducing the existing rural-urban disparity.

Background: Social media is a fast-changing, normalized way through which youth access health and nutrition information. Yet, social media content that lacks expertise or altruistic motives can negatively impact this vulnerable population through mis- or disinformation. Aim: The aims of this study were to 1) assess how adolescents and young adults engage with nutrition information across social media platforms and account types, and 2) describe their preferences for nutrition social media content. Methods: We conducted an exploratory mixed methods study with 57 undergraduate students enrolled in an introductory public health nutrition course. First, we calculated descriptive statistics on close-ended survey data on social media use and sociodemographic variables. Then, we performed thematic analysis on open-ended survey data regarding social media use, preferences, and experiences. Results: The median age of participants was 20 years old; 70% of participants identified as female and 11% identified as male. We found that TikTok and Instagram were highly preferred by participants for weight loss, wellness, diet promotion, and sports and fitness topics. In general, participants reported wanting personalized content that conveys positive nutrition messages that are supported by credible expertise. Conclusion: These findings suggest that the nutrition community can engage adolescents and young adults by presenting information as image- and video-based content on social media. Social media content related to weight loss, wellness, diet promotion, and sports and fitness topics should establish credibility using visible markers and embrace body positive messaging for maximum uptake.
