BACKGROUND Picky eating is a commonly observed behavior among children globally,negatively impacting their physical and mental growth.Although common characteristics distinguish peaky eaters,including food selectivity,food neophobia,and food avoidance,there is no clear definition to assess this behavior.Due to the unavailability of data regarding picky eating,it wasn’t easy to estimate its prevalence.AIM To develop a regional protocol to help healthcare professionals identify and manage mild and moderate picky eating cases.METHODS A virtual roundtable discussion was held in April 2021 to gather the opinions of seven pediatricians and two pediatric dietitians from eight Middle Eastern countries who had great experience in the management of picky eating.The discussion covered different topics,including clearly defining mild and moderate picky eating,identifying the role of diet fortification in these cases,and the possibility of developing a systematic approach to diet fortification.RESULTS The panel identified picky eating as consuming an inadequate amount and variety of foods by rejecting familiar and unfamiliar food.Most of the time,moderate picky eating cases had micronutrient deficiencies with over-or undernutrition;the mild cases only showed inadequate food consumption and/or poor diet quality.Paying attention to the organic red flags like growth faltering and development delay and behavioral red flags,including food fixation and anticipatory gagging,will help healthcare professionals evaluate the picky eaters and the caregivers to care for their children.Although dietary supplementation and commercial food fortification play an important role in picky eating,they were no benefit in the Middle East.CONCLUSION The panel agreed that food fortification through a food-first approach and oral nutritional supplements would be the best for Middle Eastern children.These recommendations would facilitate identifying and managing picky-eating children in the Middle East. 展开更多

PICK1蛋白是一个从线虫到人都高度保守膜周蛋白,在多种组织中表达,尤以脑和睾丸的表达最高。在细胞内,PICK1定位于核周区和诸如神经突触的特化细胞结构中。PICK1蛋白含一个PDZ结构域和一个BAR结构域,PDZ结构域能和许多膜蛋白结合,而BAR结构域能与脂质分子(主要为磷酸肌醇)相结合,通过这种机制PICK1可调节相关蛋白的亚细胞定位和膜表达。由于各蛋白与PICK1相互作用的PDZ结合基序不同,可利用与特定蛋白结合基序相同的PDZ结合多肽竞争性地结合PDZ结构域,特异性地阻断该蛋白的作用,从而特异性地增强或减弱PICK1在某组织中的作用,为PICK1的临床应用提供了药理基础。 展开更多
