Food insecurity is a growing public health concern, particularly among vulnerable groups such as adolescents, and it has been linked to poor nutritional outcomes and increased risk of chronic diseases. The Mediterranean diet (MedDiet) is recognized for its numerous health benefits, yet few studies have explored the association between food insecurity and adherence to the MedDiet among adolescents, especially in Mediterranean regions., Objective: This study aimed to investigate the association between food insecurity and adherence to the MedDiet in a sample of adolescents from Spain., Methods: Data were acquired from 2021-2022 school years from adolescents aged 12-17 years enrolled in different secondary schools in Valle de Ricote , Region of Murcia, Spain. Food security was assessed via the Spanish Child Food Security Survey Module (CFSSM-S), and adherence to the MedDiet was assessed via the Mediterranean Diet Quality Index for Children and Adolescents (KIDMED). A total of 836 participants were involved, and statistical analyses were conducted via linear regression models adjusted for lifestyle, anthropometric, and sociodemographic covariates., Results: After adjusting for potential confounders, the mean KIDMED score was 7.0 (95% confidence interval [CI] 6.7 to 7.2) in the food-security group, 6.8 (95% CI 6.3 to 7.3) in the low-security group, and 5.9 (95% CI 4.9 to 6.9) in the very-low-security group. Notable differences were observed between participants with food security and their counterparts with very low food security ( p = 0.040). Compared with those with food security (57.2%, 95% CI 51.5% to 62.8%), a significantly greater likelihood of having nonoptimal adherence to the MedDiet was identified in adolescents with low food security (61.6%, 95% CI 50.4% to 71.8%) and in those with very low food security (77.4%, 95% CI 54.5% to 90.7%). We identified a significant difference only between adolescents with food security and their peers with very low food security ( p = 0.036)., Conclusions: The findings suggest that very low food security negatively impacts MedDiet adherence in adolescents. Compared with their food-secure peers, adolescents with very low food security showed significantly poorer diet quality. These results highlight the importance of addressing food insecurity through low-cost, high-nutrition programs aimed at improving healthy eating habits, particularly for children and adolescents living in low-food-security households.

This study aims to examine the association between different versions of a provegetarian food pattern and micronutrient adequacy in a population of children from the SENDO Project. Children aged 4-5 years old were recruited and baseline information on diet, lifestyle and socio-demographic characteristics was collected through self-administered online questionnaires completed by their parents. Scores were calculated for overall, healthful, and unhealthful provegetarian food patterns (FP) using an a priori approach. Participants were categorized into tertiles according to their scores. Micronutrient adequacy was assessed using the Estimated Average Requirement (EAR) cut-off point. Multivariate analyses were performed to evaluate the relationship between tertiles of each provegetarian FP and the risk of inadequate micronutrient intake (failing to meet ≥ 3 requirements). Despite lower intakes of certain micronutrients, children with higher scores in the healthful provegetarian FP did not exhibit a higher prevalence of inadequacy. Children in the highest tertile of this index had 0.47-fold lower odds (95%CI 0.23-0.95) of having ≥ 3 inadequate micronutrient intakes than their peers in the lowest tertile, after adjusting for potential confounders. In contrast, children in the highest tertile of the unhealthful provegetarian FP had 20.06-fold higher odds (95%CI 9.19-43.79) of having ≥ 3 inadequate micronutrient intakes compared to children in the lowest tertile., Conclusions: Adherence to a healthful provegetarian food pattern is associated with improved nutritional adequacy in preschoolers, while following an unhealthful pattern is detrimental to micronutrient adequacy. These results suggest that moderate reductions in animal food consumption within a healthy diet may not compromise micronutrient adequacy in young children. Further research is needed to explore the impact of diets reduced in animal food intake on the health of children., What Is Known: • There's a notable trend towards plant-based diets due to health and sustainability concerns. • Research links plant-based diets in adults with lower risks of obesity, cardiovascular disease, and cancer., What Is New: • A new study examines how different versions of a provegetarian food pattern affect micronutrient adequacy in children, using a moderate and stepwise approach. • Following a healthful provegetarian food pattern enhances nutritional adequacy in preschoolers, whereas an unhealthful pattern negatively impacts micronutrient adequacy., (© 2024.

Objective: To analyse the feasibility and acceptability of a culinary nutritional intervention aimed at increasing plant-based foods consumption in the context of the Mediterranean diet in parent-child dyads., Design: The Nutritional and Culinary Habits to Empower Families (n-CHEF) is a 9-month feasibility study that included four culinary nutritional workshops (two face to face, two online) led by a chef and a dietitian-nutritionist. These workshops combined cooking with plant-based foods, with nutritional advice and experimental activities. The main outcomes were retention, quality of the intervention (monitoring workshops, acceptability and perceived impact) and changes in dietary and cooking habits., Setting: Parent-child dyads, Spain., Participants: Parent-child (aged 10-14 years) dyads., Results: Fifteen parent-child dyads were recruited, of which thirteen were retained during the 6-month follow-up. All but one parent-child dyads attended the four workshops. The overall assessment of the workshops was positive, although the online workshops were rated lower than the face to face. In general, parent-child dyads reported benefits in terms of nutrition and cooking aspects. Parents significantly increased their adherence to the Mediterranean diet, but non-significant changes were observed in children. However, children increased their consumption of vegetables and legumes and reduced snacks and ready meals. Parents also changed some of their culinary habits and increased their confidence in cooking at home., Conclusions: The n-CHEF showed that the culinary nutritional intervention had good levels of recruitment, retention and acceptability among parent-child dyads. In addition, dietary and culinary knowledge and habits can be improved, although further studies are needed to know the long-term effects in larger populations.

Background & Aims: The double burden of malnutrition compels us to reconsider macronutrients from a diet quality perspective. The Macronutrient Quality Index (MQI) has been designed to reflect overall macronutrient quality and is based on three sub-indexes: the carbohydrate quality index (CQI), the healthy plate protein quality index (HPPQI) and the fat quality index (FQI). Nutritional adequacy is an essential aspect of diet quality that should be captured by reliable dietary indexes., Methods: We analyzed the association between the Macronutrient Quality Index (MQI) and micronutrient adequacy. Participants were children aged 4 and 5 years, recruited in the SENDO cohort. Baseline information was collected through a self-administered online questionnaire, which included information on sociodemographic, dietary, and lifestyle variables. Dietary information was obtained using a 147-item validated semi-quantitative food frequency questionnaire. Participants were categorized into tertiles based on their MQI score. We evaluated the intake of 20 micronutrients and assessed the probability of micronutrient adequacy using the Estimated Average Requirement cut-off point., Results: Children in the highest tertile of MQI had 0.33-fold lower odds (95%CI 0.17-0.66) of having ≥3 inadequate micronutrient intakes than their peers in the lowest tertile, after adjusting for potential confounders. The adjusted proportions of children with inadequate intake of ≥3 micronutrients were 18%, 14% and 11% in the first, second, and third tertiles of MQI respectively. The MQI appears to be capable of capturing nutrient adequacy in children, although our results suggest that a modified MQI, with eggs and dairy products weighted positively, might be more adequate for the pediatric population., Competing Interests: Declaration of competing interest The authors declare no conflict of interest., (Copyright © 2024 The Author(s).

Objective: The aim of this study was twofold: first, to examine the association between perceived barriers to physical activity (PA) practice and depression, anxiety and stress in a sample of Spanish adolescents; and second, to determine which barriers are specifically associated with depression, anxiety and stress., Methods: This cross-sectional study was conducted with 765 adolescents aged 12-17 (55.6% girls) in the Valle of Ricote , Murcia, Spain. Depression, anxiety and stress symptoms were assessed using the Depression, Anxiety and Stress Scale (DASS-21), with validated cut points employed to determine the presence of each of these mental conditions. The perception of barriers to PA was assessed using a validated questionnaire for the Spanish adolescent population., Results: The barrier 'Because I feel that my physical appearance is worse than that of others' was related to a higher likelihood of having depression (OR=2.41; 95% CI 1.35 to 4.28; p=0.003), anxiety (OR=2.65; 95% CI 1.51 to 4.71; p=0.001) and stress (OR=2.82; 95% CI 1.59 to 5.07; p<0.001). Similarly, the barrier 'Because nobody encourages me to engage in physical activity' was related to a higher likelihood of having depression (OR=1.92; 95% CI 1.08 to 3.43; p=0.026), anxiety (OR=1.97; 95% CI 1.11 to 3.50; p=0.021) and stress (OR=1.99; 95% CI 1.12 to 3.59; p=0.021)., Conclusion: Perceived barriers to PA related to physical appearance and social support seem to be associated with a greater likelihood of depression, anxiety and stress among Spanish adolescents., Competing Interests: None declared., (Copyright © Author(s) (or their employer(s)) 2024.

Background: Eating habits established during the preschool stage may last a lifetime, underlining the importance of choosing and purchasing healthy foods for proper nutrition. Aim: To assess the associations between place of food purchase and dietary intake and quality in Spanish preschool children. Methods: A cross-sectional analysis was carried out within the framework of the SEguimiento del Niño para un Desarrollo Óptimo ( SENDO ) project. Data were collected using (1) the food frequency questionnaire (FFQ), from which dietary nutrient intake and diet quality (NOVA System classification and KIDMED index) were analysed, and (2) the baseline food habits questionnaire, which asked about the food purchase outlet. Data were analysed by logistic regression, considering the intra-group correlation between siblings and using the type of food purchase outlet as a grouping variable. Results: Children from families shopping in hypermarkets consumed fewer nutrients, less minimally processed foods, as well as less fruit and vegetables than children from families shopping in specialised shops. Conclusions: Food shopping in specialised outlets can improve the quality of children's diets, promoting healthier habits such as greater adherence to the Mediterranean Diet and increasing the consumption of minimally processed foods. This has a positive impact on children's long-term health.

Background: Neonatal surgical pathology presents highly technical complexity and few opportunities for training. Many of the neonatal surgical entities are not replicable in animal models. Realistic 3D models are a cost-effective and efficient alternative for training new generations of pediatric surgeons. Methods: We conceptualized, designed, and produced an anatomically realistic model for the open correction of jejunoileal atresia. We validated it with two groups of participants (experts and non-experts) through face, construct, and content validity questionnaires. Results : The model was validated by eleven experts and nine non-experts. The mean procedure time for the experts and non-experts groups was 41 and 42 min, respectively. Six non-experts and one expert did not complete the procedure by the designed time (45 min) ( p = 0.02). The mean score of face validity was 3.1 out of 4. Regarding construct validity, we found statistically significant differences between groups for the correct calculation of the section length of the antimesenteric border (Nixon's technique) ( p < 0.01). Concerning content validity, the mean score was 3.3 out of 4 in the experts group and 3.4 out of 4 in the non-experts group. Conclusions: The present model is a realistic and low-cost valid option for training for open correction of jejunoileal atresia. Before drawing definitive conclusions, future studies with larger sample sizes and blinded validators are needed.

Background: The technical complexity and limited casuistry of neonatal surgical pathology limit the possibilities of developing the necessary technical competencies by specialists in training. Esophageal atresia constitutes the paradigm of this problem. The use of synthetic 3D models for training is a promising line of research, although the literature is limited., Methods: We conceptualized, designed, and produced an anatomically realistic model for the open correction of type III oesophageal atresia. We validated it with two groups of participants (experts and non-experts) through face, construct, and content-validity questionnaires., Results: The model was validated by nine experts and nine non-experts. The mean procedure time for the experts and non-experts groups was 34.0 and 38.4 min, respectively. Two non-experts did not complete the procedure at the designed time (45 min). Regarding the face validity questionnaire, the mean rating of the model was 3.2 out of 4. Regarding the construct validity, we found statistically significant differences between groups for the equidistance between sutures, 100% correct in the expert group vs. 42.9% correct in the non-expert group (p = 0.02), and for the item "Confirms that tracheoesophageal fistula closure is watertight before continuing the procedure", correctly assessed by 66.7% of the experts vs. by 11.1% of non-experts (p = 0.05). Concerning content validity, the mean score was 3.3 out of 4 for the experts and 3.4 out of 4 for the non-experts., Conclusions: The present model is a cost-effective, simple-to-produce, and validated option for training open correction of type III esophageal atresia. However, future studies with larger sample sizes and blinded validators are needed before drawing definitive conclusions., (© 2024. The Author(s).)

Introduction: Background: this study aimed to assess how the COVID-19 lockdown (March to June 2020) affected children's sleep quality, physical activity, screen time, and nutrition. Material and methods: the survey consisted of 479 children from the SENDO project, a pediatric cohort in Spain, aged 4-5 years. The BEAR questionnaire was used to evaluate sleep quality. Hierarchical models with two-level clustering were used to account for intra-cluster correlation between siblings, and the difference regression method was used to study the association between changes in screen consumption and physical activity and changes in sleep quality. Results: the results showed an increase in the consumption of homemade pastries and snacks. Sleep quality worsened significantly during confinement, with a mean score on the BEAR scale of 0.52 before, 1.43 during, and 1.07 after confinement. Although sleep quality improved significantly after the end of confinement, it remained worse than before. The average daily screen time increased from 1.13 hours before confinement to 2.65 hours during confinement. Physical activity decreased during confinement, with the mean number of hours per day decreasing from 1.27 to 0.79. Children who spent more time on screens during confinement had worse sleep quality, as indicated by their higher scores on the BEAR scale. We used the difference regression method to identify a statistically significant association between the increased screen time for leisure hours and the worsening of children's sleep quality during confinement. Conclusion: we observed a significant relationship between confinement and reduced sleep quality. Although the end of the lockdown led to a slight improvement, the average BEAR scale score remained higher post-confinement, suggesting that the consequences of the lockdown may persist over time.

Introduction: Leucine-rich alpha-2-glycoprotein 1(LRG-1) is a human protein that has shown potential usefulness as a biomarker for diagnosing pediatric acute appendicitis (PAA). This study aims to validate the diagnostic performance of serum LRG-1 in PAA. Material and Methods: This work is a subgroup analysis from BIDIAP (BIomarkers for DIagnosing Appendicitis in Pediatrics), a prospective single-center observational cohort, to validate serum LRG-1 as a diagnostic tool in PAA. This analysis included 200 patients, divided into three groups: (1) healthy patients undergoing major outpatient surgery ( n = 56), (2) patients with non-surgical abdominal pain ( n = 52), and (3) patients with a confirmed diagnosis of PAA ( n = 92). Patients in group 3 were divided into complicated and uncomplicated PAA. In all patients, a serum sample was obtained during recruitment, and LRG-1 concentration was determined by Enzyme-Linked ImmunoSorbent Assay (ELISA). Comparative statistical analyses were performed using the Mann-Whitney U, Kruskal-Wallis, and Fisher's exact tests. The area under the receiver operating characteristic curves (AUC) was calculated for all pertinent analyses. Results: Serum LRG-1 values, expressed as median (interquartile range) were 23,145 (18,246-27,453) ng/mL in group 1, 27,655 (21,151-38,795) ng/mL in group 2 and 40,409 (32,631-53,655) ng/mL in group 3 ( p < 0.0001). Concerning the type of appendicitis, the serum LRG-1 values obtained were 38,686 (31,804-48,816) ng/mL in the uncomplicated PAA group and 51,857 (34,013-64,202) ng/mL in the complicated PAA group ( p = 0.02). The area under the curve (AUC) obtained (group 2 vs. 3) was 0.75 (95% CI 0.67-0.84). For the discrimination between complicated and uncomplicated PAA, the AUC obtained was 0.66 (95% CI 0.52-0.79). Conclusions: This work establishes normative health ranges for serum LRG-1 values in the pediatric population and shows that serum LRG-1 could be a potentially helpful tool for diagnosing PAA in the future. Future prospective multicenter studies, with the parallel evaluation of urinary and salivary LRG-1, are necessary to assess the implementability of this molecule in actual clinical practice.

A common immune-related adverse event (irAE) with immune checkpoint inhibitors (ICIs) is thyroid dysfunction (TD-irAEs). The clinical presentation can be varied, and its association with prognosis remains unclear. We investigated the characteristics of TD-irAEs and their association with clinical outcomes among cancer patients treated with ICIs in a real-life setting. Response to treatment was assessed using RECIST v1.1. We calculated the probability of recurrence and survival associated with TD-irAEs using multivariable-adjusted regression and Cox proportional hazards models. In this single-center retrospective analysis, we included 238 patients (72% male) with a median age of 69.5 years. Primary tumors were melanoma (23.1%), lung (60.5%), or urothelial cancer (16.4%), treated with atezolizumab (23.1%), pembrolizumab (44.5%), ipilimumab (0.4%), and/or nivolumab (25.6%). Seventy (29%) patients developed TD-irAEs in a median time of 69 days (41-181). The incidence of TD-irAEs with combination therapy was higher than with monotherapy (67% vs 6.3%, P = 0.011). TD-irAE patients showed a higher objective response rate (ORR) than those without TD-irAEs (60% vs 42.3%, P = 0.013) and longer overall survival (OS) 45 vs 16 months, P < 0.006. Patients who developed TD-irAEs had a relative reduction of 77% (OR 0.23, 95% CI 0.11-0.47) in the risk of progression and of 47% in the risk of mortality (HR 0.53, 95% CI 0.36-0.80), independent of age, sex, primary tumor, or ICI regimen. TD-irAEs occur in nearly 30% of our patients receiving ICIs. In our analysis, TD-irAEs appeared to be associated with higher ORR and longer OS and showed a reduction in the risk of progression and mortality.

Background: The consumption of ultra-processed foods (UPFs) is associated with an increased risk of noncommunicable diseases and mortality in adults. The aim of this study was to analyse the association between mealtime television (TV) watching and UPF consumption in childhood., Materials and Methods: Participants in the SENDO project recruited in 2015-2023 were classified into three categories based on the frequency at which they watched TV during meals. Dietary information was collected with a validated 147-item semi-quantitative food frequency questionnaire. Generalized mixed models were used to compare mean UPF consumption between groups after accounting for the main confounders. The predictive margins of participants who had a free sugar intake >10% of their energy intake in each category were also calculated., Results: Totally 970 subjects (482 girls) with a mean age of 5.00 years (SD = 0.85) were studied. Children who watched TV during meals ≥4 times/week consumed a mean of 4.67% more energy from UPF than those who watch TV <3 times/month. The adjusted proportions of children who had a free sugar intake >10% of their energy intake in the categories of <3 times/month, 1-3 times/week and ≥4 times/week exposure to TV during meals were 44.9%, 45.9% and 58.7%, respectively., Conclusion: TV watching during meals is associated with higher consumption of UPFs and a higher risk of exceeding 10% of TEI in free sugar intake in childhood., (© 2024 The Author(s).

Objective: This study tried to examine the association between the frequency of family meals and excess weight using large and representative samples of children and adolescents from 43 countries., Methods: This cross-sectional study used data from the Health Behaviour in School-aged Children (HBSC), which included nationally representative samples of children and adolescents aged 10-17 years, involving a total of 155 451 participants (mean age = 13.6 years; standard deviation [SD] = 1.6; 51.4% girls). Family meal frequency was gauged through the following question: 'How frequently do you and your family typically share meals?' The possible responses were: 'never', 'less often', 'approximately once a week', 'most days' and 'every day'. The body weight and height of the participants were self-reported and utilized to calculate body mass index (BMI). Subsequently, BMI z-scores were computed based on the International Obesity Task Force criteria, and the prevalence of excess weight was defined as +1.31 SD for boys and + 1.24 SD for girls, with obesity defined as +2.29 SD for boys and + 2.19 SD for girls. Generalized linear mixed models were conducted to examine the associations between the frequency of family meals and excess weight or obesity., Results: The lowest predicted probabilities of having excess weight and obesity were observed for those participants who had family meals every day (excess weight: 34.4%, 95% confidence interval [CI] 31.4%-37.5%; obesity: 10.8%, 95% CI 9.0%-13.0%)., Conclusions: A higher frequency of family meals is associated with lower odds of having excess weight and obesity in children and adolescents., (© 2024 The Authors.

The aim of this study was twofold: (1) to assess the association between meeting all three 24-h movement recommendations and adherence to the Mediterranean diet (MedDiet) in early childhood and (2) to examine whether participants who meet all three 24-h movement recommendations have greater adherence to the individual MedDiet foods/components than those who do not meet these recommendations. A cross-sectional study was conducted using a sample of 822 participants from the Seguimiento del Niño para un Desarrollo Óptimo (SENDO) project (Pamplona, Spain). Physical activity was assessed through a questionnaire that covered 17 different types of activities. Screen time was assessed by averaging the daily hours spent on activities such as watching TV, using a computer, or playing video games. Sleep duration was determined by taking the average of sleep durations during both weekdays and weekends. Adherence to the MedDiet was evaluated using the Mediterranean Diet Quality Index in children and adolescents (KIDMED). Greater odds of having an optimal adherence to the MedDiet were found for participants meeting all three 24-h movement recommendations (odds ratio (OR) = 1.96, 95% confidence interval (CI) 1.33-2.87, p = 0.001) in comparison with their counterparts not meeting these recommendations. Specifically, significant differences were found for "fruit or fruit juice every day" (p = 0.012), "second fruit every day" (p = 0.001), and "fresh or cooked vegetables regularly once a day" (p = 0.018) in relation to meeting all three 24-h movement recommendation status.    Conclusions: This study provides further evidence of the potential importance of meeting all three 24-h movement recommendations to adopt a healthier eating pattern. What is Known: • Only a limited number of studies have investigated the joint connection between the 24-h movement recommendations and dietary habits. • Integrating the 24-h movement recommendations with dietary recommendations could potentially yield greater effectiveness compared to promoting these recommendations independently within public health strategies. What is New: • This is the first study in assessing the relationship between 24-h movement recommendations and adherence to the Mediterranean diet in early childhood. • These findings provide further evidence of the potential importance of meeting all three 24-h movement recommendations to adopt a healthier eating pattern., (© 2024.

Background: Pop-off mechanisms are potential pressure-relieving mediators in patients diagnosed with posterior urethral valves (PUV). This systematic review aimed to synthesize the existing evidence regarding the protective effect of pop-off mechanisms on renal function in children with PUV., Methods: We conducted a systematic review of the literature that involved an extensive search in the main databases of the medical bibliography. Three independent reviewers selected the relevant articles. Methodological quality was rated using the Newcastle Ottawa Scale index. We used random meta-analyses to compare different outcomes (serum creatine, Nadir serum creatinine, and Chronic Kidney Disease) between children with PUV and pop-off mechanisms and those with PUV without pop-off mechanisms., Results: 10 studies with data from 896 participants were included in this review. Seven articles reported serum creatinine values for each group and 3 of them found significant differences between groups. The random-effects meta-analysis for serum creatinine showed significant lower mean (diff = -52.88 μmol/L [95 % CI -73.65 to -32.11]) in the group of children with pop-off mechanisms, and the random-effects meta-analysis for Nadir serum creatinine showed a marginally significantly lower mean in the group of children with pop-off mechanisms (diff = -12.00 μmol/L [95 % CI -24.04 to 0.04]). The random-effect meta-analysis for Chronic Kidney Disease resulted in a significant risk reduction for the group of children with pop-off mechanisms (odds ratio = 0.48 [95 % CI 0.23 to 0.98])., Conclusions: Children with PUV and pop-off mechanisms show better renal function and lower risk of Chronic Kidney Disease than those with PUV without pop-off mechanisms suggesting these mechanisms may act as renoprotective mediators. The high heterogeneity between studies in the assessment of renal function and long-term outcomes calls for a cautious interpretation of these findings. Future studies that stratify by different types of pop-off mechanisms and use standardized metrics, such as Nadir creatinine, are needed., Competing Interests: Conflict of interest The authors declare that they have no conflict of interest., (Copyright © 2023 The Author(s).

Objective: To assess whether the Mediterranean Diet (MedDiet) is associated with lower micronutrients inadequacy in a sample of Spanish preschoolers., Design: We conducted a cross-sectional study with 4-5-year-old children participating in the SENDO project. Information was gathered through an online questionnaire completed by parents. Dietary information was collected with a previously validated semi-quantitative FFQ. The estimated average requirements or adequate intake levels as proposed by the Institute of Medicine were used as cut-off point to define inadequate intake., Statistical Analyses: Crude and multivariable adjusted estimates were calculated with generalised estimated equations to account for intra-cluster correlation between siblings., Participants: We used baseline information of 1153 participants enrolled in the SENDO project between January 2015 and June 2022., Main Outcomes Measures: OR and 95 % CI of presenting an inadequate intake of ≥ 3 micronutrients associated with the MedDiet., Results: The adjusted proportion of children with inadequate intake of ≥ 3 micronutrients was 27·2 %, 13·5 % and 8·1 % in the categories of low, medium and high adherence to the MedDiet, respectively. After adjusting for all potential confounders, children who had a low adherence to the MedDiet showed a significant lower odds of inadequate intake of ≥ 3 micronutrients compared to those with a high adherence (OR 9·85; 95 % CI 3·33, 29·09)., Conclusion: Lower adherence to the MedDiet is associated with higher odds of nutritional inadequacy.

Background: Breastfeeding has been linked to a higher consumption of fruit and vegetables at ages 4 to 5 years. More recently, it has been suggested that it may also be associated with lower ultraprocessed food (UPF) consumption in childhood., Objective: The aim of this study was to assess whether breastfeeding duration was associated with consumption of UPF in a sample of Mediterranean preschoolers., Design: This study involved a cross-sectional analysis of baseline information of children in the Child Follow-Up for Optimal Development cohort. Children were enrolled at ages 4 to 5 years and information was gathered through an online questionnaire completed by parents. Dietary information was collected with a previously validated semi-quantitative food frequency questionnaire and foods were classified based on the degree of processing according to the NOVA classification., Participants/setting: This study used baseline information for 806 participants enrolled in the Child Follow-Up for Optimal Development cohort between January 2015 and June 2021 in Spain., Main Outcomes Measures: Main study outcome measures were difference in grams per day and in the percentage of total energy intake from UPF consumption related to breastfeeding duration, and odds ratio that UPF represents a high percentage of total energy intake., Statistical Analyses: Crude and multivariable adjusted estimates were calculated with generalized estimating equations to account for intracluster correlation between siblings., Results: The prevalence of breastfeeding in the sample was 84%. After adjusting for potential confounders, children who were breastfed for some time reported significantly lower consumption of UPF than children who were not breastfed at all. The mean differences were -19.2 g (95% CI -44.2 to 10.8) for children who were breastfed for <6 months, -42.5 g (95% CI -77.2 to -7.80) for those who were breastfed for 6 to 12 months, and -43.6 g (95% CI -79.8 to -7.48) for those who were breastfed for 12 months or more (P value for trend = 0.01). After adjusting for potential confounders, compared with children who were not breastfed, those who were breastfed for ≥12 months had consistently lower odds of UPF representing more than 25%, 30%, 35%, and 40% of total energy intake., Conclusions: Breastfeeding is associated with lower consumption of UPF in Spanish preschoolers., (Copyright © 2023 Academy of Nutrition and Dietetics.

Suboptimal micronutrient intake in children remains a public health concern around the world. This study examined the relationship between a previously defined dietary carbohydrate quality index (CQI) and the risk of micronutrient intake inadequacy in a pediatric cohort of Spanish preschoolers. Children aged 4-5 years old were recruited at their medical center or at school, and information on sociodemographic, dietary, and lifestyle variables were collected through a self-administered online questionnaire. Dietary information was obtained from a validated 147-item semi-quantitative food frequency questionnaire. We calculated the CQI and categorized participants into quartiles according to their scores. We assessed the intakes of 20 micronutrients and evaluated the probability of intake inadequacy by using the estimated average requirement cut-off point. Generalized estimating equations were used to adjust for potential confounders and account for the intra-cluster correlations between siblings. The adjusted proportions of children with an inadequate intake of ≥three micronutrients were 23%, 12%, 11%, and 9% in the first, second, third, and fourth quartiles of the CQI, respectively. Children in the highest quartile of the CQI had 0.22-fold lower odds (95% CI 0.10-0.48) of having ≥three inadequate micronutrient intakes than their peers in the lowest quartile. These findings reinforce the relevance of carbohydrate quality in children's diets.

Introduction: Scientific literature regarding the characterization of lymphocyte subpopulations of the cecal appendix is sparse, with few precedents limited to immunohistochemical techniques., Methods: We conducted a prospective pilot study to characterize lymphocyte subpopulations of the cecal appendix in children. Participants were divided into three groups: (1) patients without histological acute appendiceal inflammation, (2) patients with histological uncomplicated acute appendicitis, and (3) patients with histological complicated acute appendicitis (gangrenous, perforated). A fresh sample of the base of the appendix was taken from all patients and a flow cytometric study was performed. Quantitative variables were compared using Kruskal-Wallis test and Mann-Whitney U test., Results: This study included 57 patients divided into Group 1 (n = 5), Group 2 (n = 37), and Group 3 (n = 15). Median values (IQR) of the percentage of B-lymphocytes were 67.8 [66.8-68.1] in group 1, 61.15 [53.74-66.4] in group 2, and 52.1 [33-62.02] in group 3 (p = 0.02). Median values (IQR) of the percentage of NK-lymphocytes were 0.26 [0.2-0.3] in group 1, 0.55 [0.37-0.66] in group 2, and 0.84 [0.35-1.45] in group 3 (p = 0.008). Median values (IQR) of the percentage of T-lymphocytes were 31.9 [31.7-33.1] in group 1, 37.68 [32.15-45.69] in group 2, and 46.9 [37.03-67] in group 3 (p = 0.02). Pair comparisons of groups 2 and 3 also showed significant differences in the percentage of B lymphocytes (p = 0.03) and NK-lymphocytes (p = 0.02)., Conclusions: Significant differences in lymphocyte subpopulations were identified according to the histologic grade of the cecal appendix. More specifically, a lower percentage of B-lymphocytes and a higher percentage of T- and NK-lymphocytes were observed in cases of acute appendicitis. These findings must be confirmed and their etiopathogenic, diagnostic, and prognostic implications elucidated in future studies with larger sample sizes., (© 2023. The Author(s).)
