RESUMO
BACKGROUND: IgE-mediated food allergy (FA) is a global health concern with substantial individual and societal implications. While diverse intervention strategies have been researched, inconsistencies in reported outcomes limit evaluations of FA treatments. To streamline evaluations and promote consistent reporting, the Core Outcome Measures for Food Allergy (COMFA) initiative aimed to establish a Core Outcome Set (COS) for FA clinical trials and observational studies of interventions. METHODS: The project involved a review of published clinical trials, trial protocols and qualitative literature. Outcomes found as a result of review were categorized and classified, informing a two-round online-modified Delphi process followed by hybrid consensus meeting to finalize the COS. RESULTS: The literature review, taxonomy mapping and iterative discussions with diverse COMFA group yielded an initial list of 39 outcomes. The iterative online and in-person meetings reduced the list to 13 outcomes for voting in the formal Delphi process. One more outcome was added based on participant suggestions after the first Delphi round. A total of 778 participants from 52 countries participated, with 442 participating in both Delphi rounds. No outcome met a priori criteria for inclusion, and one was excluded as a result of the Delphi. Thirteen outcomes were brought to the hybrid consensus meeting as a result of Delphi and two outcomes, 'allergic symptoms' and 'quality of life' achieved consensus for inclusion as 'core' outcomes. CONCLUSION: In addition to the mandatory reporting of adverse events for FA clinical trials or observational studies of interventions, allergic symptoms and quality of life should be measured as core outcomes. Future work by COMFA will define how best to measure these core outcomes.

Addressing obesity is a critical health concern of the century, necessitating urgent attention. L-carnitine (LC), an essential water-soluble compound, plays a pivotal role in lipid breakdown via ß-oxidation and facilitates the transport of long-chain fatty acids across mitochondrial membranes. However, LC's high hydrophilicity poses challenges to its diffusion through bilayers, resulting in limited bioavailability, a short half-life, and a lack of storage within the body, mandating frequent dosing. In our research, we developed LC-loaded nanoparticle lipid carriers (LC-NLCs) using economically viable and tissue-localized nanostructured lipid carriers (NLCs) to address these limitations. Employing the central composite design model, we optimized the formulation, employing the high-pressure homogenization (HPH) method and incorporating Poloxamer® 407 (surfactant), Compritol® 888 ATO (solid lipid), and oleic acid (liquid oil). A comprehensive assessment of nanoparticle physical attributes was performed, and an open-field test (OFT) was conducted on rats. We employed immunofluorescence assays targeting CRP and PPAR-γ, along with an in vivo rat study utilizing an isolated fat cell line to assess adipogenesis. The optimal formulation, with an average size of 76.4 ± 3.4 nm, was selected due to its significant efficacy in activating the PPAR-γ pathway. Our findings from the OFT revealed noteworthy impacts of LC-NLC formulations (0.1 mg/mL and 0.2 mg/mL) on adipocyte cells, surpassing regular L-carnitine formulations' effects (0.1 mg/mL and 0.2 mg/mL) by 169.26% and 156.63%, respectively (p < 0.05).

Aim: The Planetary Health Diet Index (PHDI) is a relatively new index, and studies about its relationship with eating behaviors, nutritional status, and obesity in adults are very limited. For this reason, in this study, sustainable healthy eating behaviors of individuals and compliance of their diets with PHDI were evaluated. Methods: This cross-sectional study was conducted with 1,112 adults (70.1% women and 29.9% men with mean age = 28.7 years, SE = 9.47). Study data were obtained with the face-to-face interview method via a questionnaire including sociodemographic characteristics, anthropometric measurements, the Sustainable and Healthy Eating (SHE) Behaviors Scale, and 24-h dietary recall. PHDI was evaluated for adherence to EAT-Lancet Commission recommendations. Results: The average PHDI total score was 41.5 points. Higher SHE Behaviors Scale and PHDI scores were observed in participants with a duration of education above 8 years (p < 0.05). Those with lower SHE Behaviors Scale and PHDI scores were more likely to be obese (p < 0.001). The total PHDI score was positively associated with fiber, vitamin E, potassium, and folate, and negatively associated with pyridoxine and calcium (p < 0.05). The total SHE Behaviors Scale score was positively associated with carbohydrates, fiber, and potassium and negatively associated with pyridoxine, calcium, and energy (p < 0.05). A one-unit increase in SHE Behaviors Scale total score resulted in a 5,530 unit (95%CI: 4.652; 6.407) increase in PHDI total score and a one-unit increase in duration of education (years) resulted in a 0.660 unit (95%CI: 0.403; 0.918) increase in PHDI total score. Furthermore, a one-unit increase in Body Mass Index (BMI) (kg/m2) resulted in a - 0.218 unit (95%CI: -0.424; -0.013) decrease in PHDI total score. Conclusion: The participants' PHDI index scores were low; therefore, the adherence to the EAT-Lancet recommendation was low which might be associated with obesity. Clinical studies evaluating the effects of adherence to sustainable diets on adequate and balanced nutrition and health outcomes are recommended.
RESUMO
Obesity is considered one of the most crucial health problems of the century. Therefore, reducing obesity is critically important. Caffeine (CF) and chlorogenic acid (CLA), which are substantial components in green bean coffee which maximize thermogenesis in brown adipose tissue. In our study, we have prepared CF, CLA, and CF + CLA loaded-solid lipid nanoparticles (SLN) since the SLNs are cost-effective, tissue-localized, and highly stable. The central composite design model was preferred to select the optimized formulation. UHPLC was used for quantification related to the CF and CLA amounts. The high-pressure homogenization (HPH) method was used while SLN formulations were prepared in the presence of poloxamer® 407 (surfactant) and Compritol® 888 ATO (solid lipid). The nanoparticles were characterized, followed by the utilization of 3T3-F442A cell lines for the evaluation of the adipogenesis activity of the formulations. Then, rt-PCR and ELISA studies of adipogenic markers were conducted. After optimal formulations were selected with an average of 110.2 ± 0.1 nm, CF (1 mM) + CLA (0.5 mM)-loaded SLN formulation has been proven significantly effective by using PPAR-γ/C/EBP-a pathways. In a nutshell, our study has shown that CF + CLA loaded-SLN has been affected 45.8% times more than regular extracted coffee (p < 0.05) on the adipocyte cells.

Introduction: Background: intermittent fasting diets that reduce or completely restrict food intake for specific periods have become more popular in recent years. Fasting in Ramadan is also an example of these intermittent fasting practices. In fasting practices focusing on the duration of nutrition, less emphasis was placed on the information on the dietary pattern. Objective: this study aims to evaluate the Healthy Eating Index (HEI) and diet quality in fasting individuals in Ramadan. Material and methods: this study was a cross-sectional study, conducted with adults aged 18-65 years. Food consumption record was taken with a 24-h-record with food consumption form. Diet quality and adequacy were assessed with the HEI, Nutrient Adequacy Ratio (NAR), and Average Adequacy Ratio (MAR) from food consumption records. Results: according to study results, HEI and NAR Ca scores were statistically significantly lower in the fasting group than in the non-fasting group (p < 0.05). In the non-fasting group, HEI scores showed a negative correlation with body mass index (BMI) (kg/m2) and waist-hip ratio (r = -0.023, r = -0.148, p < 0.05). Conclusion: this study claimed that fasting might be associated with low scores of HEI. These results suggest that specific nutritional recommendations should be developed for fasting individuals.
Introducción: Introducción: las dietas de ayuno intermitente que reducen o restringen por completo la ingesta de alimentos durante periodos específicos se han vuelto más populares en los últimos años. El ayuno en Ramadán también es un ejemplo de estas prácticas de ayuno intermitente. En las prácticas de ayuno centradas en la duración de la nutrición, se ha puesto menos énfasis en la información sobre el patrón dietético. Objetivo: este estudio tiene como objetivo evaluar el índice de alimentación saludable (IAS) y la calidad de la dieta en personas en ayunas en Ramadán. Material y métodos: se trata de un estudio transversal, realizado con adultos de 18 a 65 años. El registro de consumo de alimentos se tomó con un registro de 24 horas con formulario de consumo de alimentos. La calidad y la adecuación de la dieta se evaluaron con el IAS, el índice de adecuación de nutrientes (NAR) y la ratio de adecuación promedio (MAR) de los registros de consumo de alimentos. Resultados: de acuerdo con los resultados del estudio, las puntuaciones de HEI y NAR Ca fueron estadísticamente significativamente más bajas en el grupo que hace ayuno que en el grupo sin ayuno (p < 0,05). En el grupo sin ayuno, las puntuaciones HEI mostraron una correlación negativa con el índice de masa corporal (IMC) (kg/m2) y la relación cintura-cadera (r = -0,023, r = -0,148, p < 0,05). Conclusión: este estudio afirmó que el ayuno podría estar asociado con puntuaciones bajas de IAS. Dichos resultados sugieren que se deben desarrollar recomendaciones nutricionales específicas para las personas que hacen ayuno.

Aim: Parental behaviors and the home environment are two of the most effective ways to adopt healthy eating and active lifestyles. For this reason, it is crucial to understand children's nutritional habits, analyze the dynamics related to parental factors, diagnose and treat childhood obesity in the early period, and prevent adulthood obesity. This study aimed to explore how parenting influences children's nutritional status, physical activity, and BMI. Methods: The study involved 596 children with their parents. The data were collected through face-to-face interviews using the survey method. The survey consists of descriptive information (age, gender, educational status), anthropometric measurements, nutritional habits, Family Nutrition and Physical Activity Scale (FNPA), International Physical Activity Questionnaire, and 24-h dietary recall. The Mean Adequacy Ratio (MAR) was applied to assess dietary adequacy. Results: Most mothers and fathers were overweight or obese (61.6 and 68.7%, respectively). 38.6% of boys and 23.1% of girls were overweight or obese. The FNPA score was positively correlated with MAR (p < 0.05). Multiple linear regression analysis revealed that children's BMI was negatively correlated with FNPA score, while maternal BMI and father's BMI were positively correlated (p < 0.05). Furthermore, dietary energy was not associated with the child's BMI but with dietary adequacy (p < 0.05). There was no evidence that family impacted children's physical activity. Conclusion: This study supports that parenting influences children's dietary intake and BMI. Adequate and balanced nutrition, regardless of dietary energy, may affect children's body weight. Family plays a significant role in influencing and forming children's lifestyle-related behaviors. Children's healthy eating and physical exercise habits can be encouraged through school-based programs involving families.
