Objective

Nutrition, as a cross-disciplinary field, is sometimes difficult to fully integrate into daily medical practice, despite its complementarity with many specialties. Nevertheless, its prescription remains inconsistent, and a lack of knowledge or mastery of the various forms of artificial nutrition can hinder their appropriate use. This study aims to assess medical doctor's level of knowledge regarding current recommendations on artificial nutrition.

Methods

The study was conducted among 46 medical doctor at a peripheral hospital center involved in the nutritional management of adult patients. Participants answered four open-ended questions designed to explore their knowledge of current guidelines on artificial nutrition.

Results

The findings reveal a significant gap between the most recent recommendations and medical doctor’ knowledge, which may help explain the underprescription of appropriate nutritional support. Although oral, enteral, and parenteral nutrition are generally well known, some contraindications reported by respondents are not supported by current guidelines. The precautionary principle, patient refusal, and technical difficulties are frequently cited as barriers to prescription. Enteral nutrition is preferred as the first-line approach over parenteral nutrition, but its initiation is sometimes delayed due to negative perceptions (pain, discomfort, stigma). Additionally, social and technical factors contribute to a reluctance toward enteral nutrition, leading to the use of parenteral nutrition, sometimes inappropriately.

Conclusion

This survey highlights a gap between recommendations and clinical practice, underlining the importance of ongoing theoretical and practical training in clinical nutrition throughout the care pathway. Clarifying indications, improving communication with patients, and developing decision-support tools could enhance the relevance of nutritional prescriptions. Regular training in nutrition would help align medical practices with current guidelines, optimize the management of malnourished patients, and reduce associated complications. The issue is clinical, ethical, and medico-economic.

目的营养学作为一个跨学科的领域，尽管与许多专业具有互补性，但有时很难完全融入日常医学实践。然而，它的处方仍然不一致，缺乏对各种形式的人工营养的知识或掌握会妨碍它们的适当使用。本研究旨在评估医生对目前人工营养建议的了解程度。方法对46名参与成人患者营养管理的外围医院中心医生进行调查。参与者回答了四个开放式问题，旨在探索他们对当前人工营养指南的了解程度。结果最新的建议与医生的知识之间存在显著差距，这可能有助于解释适当营养支持的处方不足。虽然口服、肠内和肠外营养通常是众所周知的，但应答者报告的一些禁忌症并没有得到现行指南的支持。预防原则、病人拒绝和技术困难经常被认为是处方的障碍。肠内营养优于肠外营养，是首选的一线治疗方法，但由于负面认知（疼痛、不适、耻辱），肠内营养有时会被推迟。此外，社会和技术因素导致不愿肠内营养，导致肠外营养的使用，有时是不适当的。结论：该调查强调了建议与临床实践之间的差距，强调了在整个护理途径中进行临床营养理论和实践培训的重要性。明确适应症，改善与患者的沟通，开发决策支持工具可以提高营养处方的相关性。定期的营养培训将有助于使医疗实践与现行指南保持一致，优化对营养不良患者的管理，并减少相关并发症。这个问题涉及临床、伦理和医学经济。

Introduction

The consumption of food supplements (FS) affects between 22% and 59% of the French adult population, for uncertain benefits and potential risks. This study aimed to describe FS consumption among adult patients in general practice, estimate its prevalence, evaluate the physician's involvement in counseling, and identify associated consumption factors.

Methods

This cross-sectional study was conducted between March and July 2023 through a self-administered questionnaire among adult patients consulting a general practitioner in Levallois-Perret (92), Île-de-France, France. Descriptive analysis and univariate associations were performed.

Results

Among the 202 participants, 55% were currently consuming FS and 25% had consumed them in the past. However, only 25% were aware of potential toxicity. On average, patients consumed 2 FS for an estimated cost of €18 per month and for 2 to 3 different health claims, mainly fatigue, sleep disorders, and aesthetic concerns. Female gender and BMI ≥ 25 kg/m² were significantly associated with aesthetic use. Male gender and regular physical activity were linked to muscle-related FS. Age was associated with cardiovascular health, aging, and joint/muscle pain. Although 66% of patients learned about FS through healthcare professionals and 82% considered it useful to discuss FS with their doctor, only 8% spontaneously disclosed their use during consultations.

Conclusion

Half of the patients consume FS, often with limited medical oversight. General practitioners have a key role in advising and monitoring, especially considering the potential risks and lack of high-quality evidence supporting FS efficacy.

食品补充剂（FS）的消费影响了22%至59%的法国成年人，其益处和潜在风险不确定。本研究旨在描述成人患者在一般实践中的FS消费，估计其患病率，评估医生参与咨询，并确定相关的消费因素。方法本横断面研究于2023年3月至7月在法国Île-de-France的勒瓦卢瓦-佩雷（Levallois-Perret, 92）的全科医生咨询的成年患者中通过自我填写的问卷进行。进行描述性分析和单变量关联分析。结果202名参与者中，55%的人正在服用FS， 25%的人曾经服用过FS。然而，只有25%的人意识到潜在的毒性。平均而言，患者每月消费2次FS，估计费用为18欧元，并且有2到3种不同的健康索赔，主要是疲劳、睡眠障碍和审美问题。女性和BMI≥25 kg/m2与审美使用显著相关。男性性别和规律的体育活动与肌肉相关的FS有关。年龄与心血管健康、衰老和关节/肌肉疼痛有关。尽管66%的患者通过医疗保健专业人员了解到FS， 82%的患者认为与医生讨论FS是有用的，但只有8%的患者在咨询期间自发地透露了他们的使用情况。结论一半的患者使用FS，往往缺乏医疗监督。全科医生在建议和监测方面发挥着关键作用，特别是考虑到潜在风险和缺乏支持FS疗效的高质量证据。

Background

Intuitive eating is the kind of eating pattern could be expressed as keeping a solid link between human body and its inside signs for hunger/satiety. This approach allows us to understand and listen to our body when it comes to food choices and improves eating behaviours.

Aim

To determine the intuitive eating score among students of Jordanian universities.

Methods

Cross-sectional survey; targets students in Jordanian (public & private) universities. Intuitive eating was measured by the “twenty-three-item Intuitive-Eating Scale-2”, (IES-2). IES-2 counts the respondents’ capability to trust body's inside hunger/satiety signals while choosing the food items they will eat to determine their intuitive eating (IE) score. The students were informed through a survey on every item to determine the best answer that best describes their eating attitudes or behaviours.

Results

There were 431 students from Jordanian public and private universities. Both groups’ Intuitive Eating Scale (IES) scores were neutral. Neither males nor females scored higher than four on the IES-2. However, male respondents’ results indicated a higher score than female respondents’ since female respondents’ results had a 3.5 score while males had a 3.67 score.

Conclusions

The results showed that all male and female respondents indicated a neutral total IES score. More studies are needed to discover if intuitive eating influences weight control behaviours and body mass index. Intuitive eating behaviour may be a better and healthier alternative to traditional diets. Individuals who eat intuitively build a stronger connection with themselves towards food.

直观饮食是一种饮食模式，可以被表达为保持人体与其内部饥饿/饱腹感信号之间的牢固联系。当涉及到食物选择时，这种方法使我们能够理解和倾听我们的身体，并改善饮食行为。目的确定约旦大学生的直观饮食得分。MethodsCross-sectional调查;目标是约旦（公立和私立）大学的学生。直觉性饮食采用“23项直觉性饮食量表-2”（IES-2）进行测量。IES-2计算受访者在选择他们将吃的食物时信任身体内部饥饿/饱腹感信号的能力，以确定他们的直觉饮食（IE）得分。学生们通过对每个项目的调查来确定最能描述他们饮食态度或行为的最佳答案。结果共有431名学生来自约旦公立和私立大学。两组的直观饮食量表（IES）得分均为中性。男性和女性在IES-2中的得分都不高于4分。但是，男性的得分高于女性，因为女性的得分为3.5分，而男性的得分为3.67分。结论所有男性和女性受访者的IES总分均为中性。直觉性饮食是否会影响体重控制行为和体重指数，还需要更多的研究来证实。直觉饮食行为可能是传统饮食更好、更健康的选择。凭直觉吃东西的人会对食物与自己建立更强的联系。

Background and aims

Our hypothesis in this study was to investigate whether there is an association between metabolic risk parameters and the MEDFICTS score (meat, eggs, dairy products, fried foods, fats in bakery products, convenience foods, added fats at table and snacks) and tinnitus severity in adults.

Methods

This descriptive study was conducted with 331 adults aged 19–64. Data were collected through face-to-face interviews using data collection forms consisting of the Tinnitus Disability Questionnaire, MEDFICTS Dietary Assessment Questionnaire, metabolic risk parameters, and anthropometric measurements. Descriptive statistics, Student's t-test, and simple and multivariate linear regression analysis were applied to data analysis. The significance level of statistical tests was accepted as P < 0.05.

Results

The mean waist circumference (WC), fasting blood glucose, High Density Lipoprotein (HDL), Triglyceride (TG), Systolic Blood Pressure (SBP), and Diastolic Blood Pressure (DBP) were 89.30 ± 13.42 cm, 96.14 ± 17.62 mg/dL, 52.34 ± 11.43 mg/dL, 127.82 ± 48.54 mg/dL, 121.29 ± 12.90 mm/Hg and 73.49 ± 9.34 mm/Hg, respectively. The mean MEDFICTS score was 78.08 ± 26.04 and 59.8% of the individuals needed dietary changes for heart health. The mean Tinnitus Disability Questionnaire total score was 40.17 ± 22.14. 2.4% had moderate tinnitus and 1.5% had severe tinnitus. Fasting blood glucose (β: 0.524, P < 0.05) and MEDFICTS score (β: 0.459, P < 0.05) were positively associated with tinnitus severity, 24% of the change in tinnitus severity was explained by fasting blood glucose, and 17% by MEDFICTS score.

Conclusion

Increased fasting blood glucose and increased dietary intake of foods high in saturated fat and cholesterol are associated with increased tinnitus severity.

背景与目的本研究的假设是调查代谢风险参数与MEDFICTS评分（肉类、鸡蛋、乳制品、油炸食品、烘焙食品中的脂肪、方便食品中的脂肪、餐桌和零食中的添加脂肪）和成人耳鸣严重程度之间是否存在关联。方法对331名19-64岁成人进行描述性研究。通过面对面访谈收集数据，数据收集表格包括耳鸣残疾问卷、MEDFICTS饮食评估问卷、代谢风险参数和人体测量。数据分析采用描述性统计、学生t检验和简单多元线性回归分析。统计学检验的显著性水平采用P <；0.05.结果平均腰围（WC）、空腹血糖、高密度脂蛋白（HDL）、甘油三酯（TG）、收缩压（SBP）、舒张压（DBP）分别为89.30±13.42 cm、96.14±17.62 mg/dL、52.34±11.43 mg/dL、127.82±48.54 mg/dL、121.29±12.90 mm/Hg和73.49±9.34 mm/Hg。MEDFICTS平均得分为78.08±26.04,59.8%的个体需要改变饮食以保持心脏健康。耳鸣残疾问卷的平均总分为40.17±22.14分。中度耳鸣2.4%，重度耳鸣1.5%。空腹血糖(β: 0.524, P <；0.05)和MEDFICTS评分(β: 0.459, P <；0.05)与耳鸣严重程度呈正相关，24%的耳鸣严重程度变化与空腹血糖有关，17%与MEDFICTS评分有关。结论空腹血糖升高、高饱和脂肪和高胆固醇食物摄入增加与耳鸣严重程度增加有关。

Objectives

To assess food habits, sleep duration and weight status of university students. Also, to investigate the impact of social media use on students’ food habits, sleeping and weight status.

Materials and methods

A cross-sectional descriptive study was conducted among 400 Algerian university students, from February 2024 to May 2024. Data related to social media usage, eating habits, physical activity and sleeping was collected. Weight and height were measured and Body mass index was calculated and classified according to the recommendations. Statistics were performed using StatviewTM and SPSS software.

Results

The majority of students (59.0%) used social media for two hours and more per day. Overweight students were significantly (P < 0.0001) the most likely to use social media platforms. Students who used social media for more than four hours were the most likely to have irregular meals (P = 0.04), to skip breakfast, lunch, dinner (P < 0.05) and to snack between meals sugary and junk foods and drink sodas (P < 0.05). Students who used social media the most were those who sleep few hours (P = <0.0001).

Conclusion

The study elucidated a complex relationship between food habits, social media usage and weight status among university students. It highlighted prevalent irregular eating patterns and frequent meal skipping, compounded by the significant impact of social media on dietary behaviors.

目的了解大学生的饮食习惯、睡眠时间和体重状况。同时，调查社交媒体使用对学生饮食习惯、睡眠和体重状况的影响。材料与方法在2024年2月至2024年5月期间对400名阿尔及利亚大学生进行了横断面描述性研究。收集了与社交媒体使用、饮食习惯、体育活动和睡眠有关的数据。测量体重和身高，计算身体质量指数，并根据建议进行分类。统计学采用StatviewTM和SPSS软件。结果大多数学生（59.0%）每天使用社交媒体的时间在2小时及以上。(P <；0.0001)最有可能使用社交媒体平台。使用社交媒体超过4小时的学生最可能饮食不规律（P = 0.04），不吃早餐、午餐和晚餐(P <；0.05)，在两餐之间吃含糖和垃圾食品，喝苏打水(P <；0.05)。使用社交媒体最多的学生是那些睡眠时间很少的学生（P = <0.0001）。结论本研究揭示了大学生饮食习惯、社交媒体使用与体重状况之间的复杂关系。它强调了普遍存在的不规律饮食模式和频繁不吃饭，加上社交媒体对饮食行为的重大影响。

We conducted a criterion-referenced search using Web of Science, Science Direct, PubMed, and Google Scholar databases, selecting a total of 19 articles according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Statistical analyses were performed using comprehensive meta-analysis (CMA) software.

Results

The results showed an estimated overall prevalence of NCGS at 6.3% (95% CI: 2.8–6.6%). The prevalence was 6.3% (95% CI: 2.6–6.8%) in adults and 2.3% (95% CI: 0.4–4.3%) in children, and higher in women than in men, 3.9% (95% CI: 1.6–5.1%) versus 2.2% (95% CI: 0.06–2.2%), respectively. In terms of country income, the prevalence of NCGS was lower in high-income countries, estimated at 2.3% (95% CI: 1.6–6.5%), than in middle- and low-income countries, with a value of 4.1% (95% CI: 2.9–8.9%).

Conclusion

This systematic and meta-analysis reveals a high prevalence of NCGS, estimated, which varies according to age, sex, and country income. This finding underlines the importance of improving diagnostic and management strategies for this clinical condition.

Eating disorders such as anorexia nervosa, bulimia nervosa and binge eating disorder, are characterized by psychopathological disorders that affect patients’ relationship to food and their body perception. These disorders have repercussions on physical, mental and oral health. Oral manifestations include changes in the salivary glands, mucous membranes, periodontal tissues and teeth. Eating disorders can lead to poor oral health by altering salivary flow, increasing oral acidity and promoting the proliferation of pathogenic bacteria. Salivary pathologies, resulting from purging behaviors and the use of certain medications, can alter taste sensitivities and lead to hyposialia, a reduction in oral pH. Mucosal injuries are often caused by iatrogenic traumas, nutritional deficiencies, and chronic irritations that may require symptomatic treatment and vitamin supplementation. Nutritional deficiencies (vitamins C, D and B) have consequences on periodontal tissues, increasing the risk of periodontitis, tooth mobility and tooth loss. Dental lesions, such as erosions, cervical tooth wear and caries lesions, result from unbalanced eating behaviors and require rigorous oral hygiene, vitamin supplementation and an early intervention to avoid severe complications. The care of patients with eating disorders requires a multidisciplinary approach, especially with the oral health, involving regular visits to the dentist and preventive measures to improve patients’ quality of life.

神经性厌食症、神经性贪食症、暴食症等进食障碍以精神病理障碍为特征，影响患者与食物的关系和身体感知。这些疾病对身体、精神和口腔健康都有影响。口腔表现包括唾液腺、粘膜、牙周组织和牙齿的变化。饮食失调会改变唾液流动，增加口腔酸度，促进致病菌的繁殖，从而导致口腔健康状况不佳。由于排便行为和使用某些药物引起的唾液病变可改变味觉敏感性并导致唾液分泌不足，口腔ph值降低。粘膜损伤通常由医源性创伤、营养缺乏和慢性刺激引起，可能需要对症治疗和补充维生素。营养缺乏（维生素C、D和B）会对牙周组织造成影响，增加牙周炎、牙齿活动和牙齿脱落的风险。牙齿损伤，如糜烂、颈牙磨损和龋齿损伤，是由不平衡的饮食行为造成的，需要严格的口腔卫生、补充维生素和早期干预，以避免严重的并发症。饮食失调患者的护理需要多学科方法，特别是口腔健康，包括定期看牙医和采取预防措施，以提高患者的生活质量。

Background and objectives

Lutein is a xanthophyll carotenoid with potential advantages for obesity and cardiometabolic disorders. The purpose of this double-blind, randomized, controlled trial was to determine whether consuming lutein alongside a low-calorie diet (LCD) affects the serum levels of leptin and adiponectin and the pro-oxidant/antioxidant balance (PAB) in obese middle-aged individuals.

Material and methods

Following a 2-week run-in phase with an LCD, 48 participants aged 45–65 were randomly assigned to take either 20 mg/d of lutein or placebo in conjunction with an LCD for 10 weeks. At the beginning and end of the study, dietary intake, anthropometric indices, serum levels of leptin and adiponectin and PAB were measured.

Results

The results showed that 10 weeks of lutein supplementation alongside an LCD diet reduced PAB compared to controls (–17.38% in lutein group vs. 21.57% in control group, P < 0.001). No significant changes were observed in the serum levels of adiponectin and leptin.

Conclusion

Lutein consumption could significantly diminish oxidative stress in obese middle-aged individuals.

背景与目的叶黄素是一种叶黄素类胡萝卜素，对肥胖和心脏代谢疾病具有潜在的优势。这项双盲、随机、对照试验的目的是确定在低热量饮食（LCD）的同时摄入叶黄素是否会影响肥胖中年个体的血清瘦素和脂联素水平以及促氧化/抗氧化平衡（PAB）。材料和方法48名年龄在45-65岁之间的参与者被随机分配到服用20毫克/天的叶黄素或安慰剂与LCD联合服用10周。在研究开始和结束时，测量饮食摄入量、人体测量指数、血清瘦素、脂联素和PAB水平。结果结果显示，与对照组相比，添加10周叶黄素并添加LCD饮食可减少PAB(叶黄素组为-17.38%，对照组为21.57%；0.001)。血清脂联素和瘦素水平未见明显变化。结论叶黄素可显著降低中年肥胖人群的氧化应激。
