Background: Chronic diseases and polymedication increase the risk of food-drug interactions (FDIs) among the population, negatively impacting health. Nutritionists, as responsible for dietary planning, have a key role in preventing these events.

Aim: To assess the knowledge about FDIs among a sample of Nutrition Sciences Bachelor students.

Methods: A descriptive cross-sectional observational study was conducted, involving 44 students from the 3^rd and 4^th academic years of different Portuguese universities during the 2023/2024 academic year. Participants completed a self-reported questionnaire, covering general and specific FDIs knowledge, academic background, and perceptions regarding FDIs importance and training adequacy.

Results: Results revealed a general lack of FDIs knowledge among participants, particularly in identifying specific interactions and appropriate dietary management. While half of the students reported exposure to a subject dedicated to FDIs, only 18.18% considered the knowledge acquired sufficient. Nearly all participants (93.18%) expressed the need for further training in FDIs during their undergraduate course. Furthermore, none of the participants had received additional training or attended workshops on FDIs. Specifically, participants struggled to identify appropriate dietary choices in conjunction with certain medications. Moreover, only a minority of participants demonstrated awareness of the ideal timing for medication intake relative to food consumption. Despite these knowledge gaps, participants recognized the importance of FDIs knowledge for future clinical practice.

Conclusion: Bridging these knowledge gaps through targeted educational interventions and interdisciplinary collaboration is essential to ensure future nutrition professionals are equipped to address the complex challenges posed by FDIs in professional practice.

Study purpose: This study aims to examine patient preferences for teleradiology services and remote image interpretation. In this context, this study aims to address the following research questions: (i) How do patients perceive teleradiology services, focusing specifically on comfort, quality of care and satisfaction, communication and information, and accessibility and ease of use; (ii) How do patient demographics (age, gender, urban vs. rural residence) influence the perceptions on teleradiology services?

Methods: A cross-sectional survey design is adopted in this study. The survey comprises five sections targeting demographic information, comfort, and preferences regarding remote image interpretation, perceived quality of care and satisfaction, communication and information clarity, and accessibility and technology aspects using five-point Likert scale ratings. A total of 406 patients (209 males and 197 females; 170 urban residents; 174 semi-urban residents, and 62 rural residents) using teleradiology services participated in the study.

Results: Participants reported high satisfaction with remote image interpretation (3.78 ± 1.19), quality of care (3.31 ± 1.19), understanding (3.84 ± 1.43), and user-friendliness (3.67 ± 1.29). Key issues were technical problems (3.81 ± 1.35), feedback difficulties (3.19 ± 1.58), privacy concerns (2.43 ± 1.46), and low awareness (2.37 ± 1.12). Urban participants scored significantly better in comfort, preferences, and communication than those from semi-urban and rural areas.

Conclusion: Teleradiology design and implementation should be optimized to align with patient preferences and enhance overall satisfaction.

Saw palmetto extract (SPE) is the most commonly used supplement for the treatment of lower urinary tract symptoms (LUTS), but most evidence is for those with LUTS, and little data is verifying its effectiveness for those who do not have the disease but are troubled by symptoms. The purpose of this study was to examine the effect of SPE on the improvement of urinary frequency problems that present stress due to urinary urgency in daily life, among healthy Japanese adults aged ≥50 years who are not diagnosed with benign prostatic hyperplasia or overactive bladder. They were randomly assigned to the SPE group or placebo group (34 participants per group) using a computerized random number generator. Each participant was instructed to take one capsule containing SPE (320 mg) or placebo every day for 12 weeks. Subjective symptoms were assessed using the overactive bladder questionnaire, and the score of symptom bother by frequent urination during the daytime hours was set as the primary outcome. The other outcomes were subjective urinary symptoms and urinary frequencies. The final efficacy analysis dataset was per protocol set, and 33 participants in each group were analyzed. After SPE intervention for 12 weeks, the score of symptom bother by frequent urination during the daytime hours was significantly improved and the daytime frequency of urination assessed using the urinary log was significantly decreased. The consumption of SPE improved urinary frequency-related quality of life such as bother of urinary symptoms in healthy Japanese adults (UMIN000045334).

Background and aim: To evaluate the validity and user satisfaction of a digital photo-based dietary assessment tool as an alternative to the hand-written paper record method that assists researchers during the pandemic. This study compared nutrient intake and users' satisfaction with methods between a digital photo-based dietary assessment tool, known as the Nutrinote Gama app, and food weighing as the gold standard. Methods: Fifty college students majoring in food and nutrition (90% were women; median age, 21 years) took pictures of their foods and beverages before and after consumption and then uploaded them to the Nutrinote Gama application. Trained nutritionists evaluated plate wastes, and nutritional content was revealed on the Nutrinote Gama application. Parallel to the photo-based method, they kept a weight dietary record and sent it to the researcher. A questionnaire was used to assess participants' satisfaction. Results: No statistical differences (p = 0.89) were observed in the measurement of energy intake between Nutrinote Gama (mean ± standard deviation [SD] = 582.8 ± 131) and food weighing (mean ± SD = 566.1 ± 133). No statistical differences (p = 0.59) were also observed in the measurement of protein, fat (p = 0.434), and carbohydrate (p = 230). The energy, protein, fat, and carbohydrate intakes estimated from the two methods were significantly correlated (r = 0.86, 0.870, 0.811, 0.738, respectively). Over 70% of participants were satisfied with the photo-based record. Conclusion: The results indicate that this digital photo-based dietary assessment tool is valid and user-friendly to estimate nutrient intake.

Background: Improving mother and child nutrition during the first 1000 days of life (DoL) is one of the major areas where mHealth has demonstrated great promise. A lot of mHealth is already used in society. However, no study examines the content and features of mobile health. Aim: This study aims to examine the difference in content and features of mHealth intervention for maternal and child nutrition throughout the first 1000 days of life. Thus, new apps can be enhanced. Methods: The online journal databases that offer free papers from Scopus-indexed journals published in 2017-2022 served as the primary sources for the literature included in this study. Several keywords were used in the literature search, which used the databases Google Scholar, Science Direct, and PubMed. A total of 8 articles were included in the literature review. Results: Existing mHealth provides content and features to support and improve the health status of pregnant women, breastfeeding mothers, and children aged 0-24 months. mHealth interventions have the potential to improve maternal and child nutrition health in the first 1000 days of life by providing education, communication, support, data collection and analysis, cultural appropriateness, accessibility, and capacity building for health workers. However, it is crucial to address challenges such as evidence-based design, privacy and security, sustainability, and data management, and to ensure cultural appropriateness and accessibility for all populations. Conclusions: The more complete the content, features, and uses of mHealth, the greater the users' acceptance.

Background: Korea's child meal support program (CMSP) aims to reduce food and nutrition insecurity (FNI) and improve health among children from low-income households.

Aim: We examined the impact of different types of CMSP on children's FNI and health in Korea, analyzing meal frequency and healthful food consumption (FNI), and general health and depression (health) among child meal card (CMC) and facility meal service (FMS) participants compared with nonparticipants.

Methods: The 2018 Comprehensive Survey on Korean Children data were analyzed. Precisely, 847 children from low-income households aged 9-17 were categorized into CMC (n = 331), FMS (n = 209), and income-eligible nonparticipants (n = 307). Propensity score-weighted generalized linear models assessed CMSP's impact on FNI and health. Stratified generalized linear models examined heterogeneity in FNI-health associations by CMSP status.

Results: CMC participants reported more frequent breakfast consumption (odds ratio [OR] = 0.662, p < 0.05) but poorer self-rated general health (OR = 1.890, p < 0.05); FMS participants were less likely to have three meals (OR = 1.814, p < 0.05), fruits and vegetables (OR = 2.194, p < 0.001), and protein-rich foods daily (OR = 1.695, p < 0.05) than nonparticipants. Health risks associated with healthful food consumption and meal frequency were more pronounced among CMC and FMS/nonparticipants, respectively.

Conclusion: CMSP had a limited impact on reducing FNI and improving health among children from low-income households. CMC appeared more effective than FMS in alleviating FNI, notwithstanding potential health concerns. Food assistance programs should seek comprehensive enhancements in children's food and nutrition security and health.

Background: Reliable and accurate estimates of body composition are essential when studying the various health correlates of disease. Bioelectrical impedance analysis (BIA) is an affordable and feasible body composition assessment technique for clinical and field settings. Total body water (TBW) and hence fat-free mass is estimated by predictive regression algorithms using anthropometric measurements plus the resistance index. Aim: The study aimed to develop a BIA prediction equation for TBW in children in Myanmar using the deuterium dilution technique as the reference method. Methods: The study design was cross-sectional in a school setting with convenience sampling of participants. One hundred and two healthy children (57 boys and 45 girls) with aged 4 and 8 years participated; randomly divided into the prediction group (29 boys and 22 girls) and cross-validation group (28 boys and 23 girls). Whole-body impedance, anthropometric and TBW (by D₂O dilution) measurements. The prediction equation was cross-validated using a split-group design and compared to published equations for contemporaneous populations. Results: TBW could be predicted by the following equation. TBW = 0.4597 * Weight (kg) + 0.1564 * Impedance index + 0.6075 (R² = 0.891, P < 0.0001) with a correlation coefficient of 0.942 and limits of agreement of 0.98 kg TBW on cross-validation. Conclusions: This equation can be used to predict body composition in young (aged 4-8 years) children in Myanmar but because the age range of the participants in the present study was relatively narrow, more research in different age groups is required to establish its broader applicability.

Background: The COVID-19 pandemic upended many aspects of daily life. For some individuals, this was an opportunity to re-evaluate their life and make better choices, while others were overwhelmed with stressors, leading to a deterioration in mental and physical health.

Aim: The aim of this narrative systematic review is to explore the effects of the COVID-19 pandemic on Mediterranean diet adherence.

Methods: A systematic literature search was carried out on PubMed, Scopus and Web of Science electronic databases utilising the search terms 'Mediterranean diet' AND 'COVID-19'. This yielded 73 articles that fulfilled the inclusion criteria.

Results: The data suggests that a substantial proportion of individuals adhered less to the Mediterranean diet during the COVID-19 lockdown period. However, individuals receiving some form of lifestyle intervention had better adherence to the Mediterranean diet than their unassisted counterparts.

Conclusion: This emphasises the importance of professional support during times of crisis to avoid deterioration of a population's health.

Background: Despite the importance of nutrition education for burn survivors, only limited work has been done to ascertain what is known about these education programs. Aim: To scope the existing literature to ascertain what is known about the nature and outcomes associated with nutrition education programs for burn survivors, their families and caregivers. Methods: Arksey and O'Malley scoping review approach were utilized with searches across peer-reviewed databases and gray literature sources. Results: Six studies were retained. Five studies focused on burn survivors and one focused on healthcare professionals. One study reported improved knowledge regarding postburn nutritional support following the implementation of the nutrition counseling program. Three studies reported on the inclusion of a nutrition education component in comprehensive postdischarge rehabilitation programs albeit no nutrition-specific outcomes were reported. Conclusion: The review affirms the limited literature, highlighting a need for more work to implement and evaluate outcomes of nutrition education programs for burn survivors.

Background: Worldwide, fruit and vegetable intake is below recommendations. There is increasing evidence to suggest an association between height and diet. Aim: to analyse the associations of fruit and vegetable intake with attained height in Portuguese adults. Methods: A representative sample of 17 480 Portuguese adults (56.7% women) participated in this cross-sectional study. The survey comprised sociodemographic characteristics and self-reported height and weight. We performed regression models to assess the associations between height and fruit and vegetable consumption. Results: Compared with no intakes, those men with higher fruit and vegetables intake had 0.54 cm (95% CI 0.04; 1.04) greater height. Also, women with higher intakes of vegetables, fruit and vegetables combined were directly associated with a greater height of 0.29 cm (95% CI 0.03; 0.56 in vegetables) and 0.51 cm (95% CI 0.09; 0.93 in fruit and vegetables combined). Conclusion: Greater consumption of fruit and vegetables was directly associated with higher height in adults. From a health promotion perspective, intervention programmes aiming at improving fruit and vegetable intake should be highlighted so that full height potential is achieved.
